[ x/(3+x) * (2+x)/(3+x) ] / (1-x)/(3+x) = 0,2336

$$[ x/(3+x) * (2+x)/(3+x) ] / (1-x)/(3+x) = 0,2336\\\\
\left[\frac{x}{(3+x)} \times \frac{(2+x)}{(3+x)}\right]\div \frac{(1-x)}{(3+x)} = 0.2336\\\\
\mbox{It should be noted straight off that }3+x\ne0\;so\;x\ne-3\\\\
\left[\frac{x}{(3+x)} \times \frac{(2+x)}{(3+x)}\right]\times \frac{(3+x)}{(1-x)} = 0.2336\qquad \mbox{the (x+3) cancels,and }x\ne1\\\\
\left[\frac{x}{(3+x)} \times \frac{(2+x)}{1}\right]\times \frac{1}{(1-x)} = 0.2336\qquad \mbox{}\\\\
\frac{x(2+x)}{(3+x)(1-x)} = 0.2336\qquad \mbox{}\\\\
\frac{x(2+x)}{(3+x)(1-x)} = 0.2336\qquad \\\\
\mbox{Now multiply everything by the lowest common denominator (3+x)(1-x) to get rid of the fraction}\\\\
x(2+x) = 0.2336(3+x)(1-x)\qquad \\\\$$

 

you can keep going from here and solve it with the quadratic formula or you can just plug your initial equation into the site calc and get it to do it all for you.  

(x/(3+x) * (2+x)/(3+x) ) / (1-x)/(3+x) = 0.2336  

change the square brackets to round ones and change your decimal comma to a decimal point and just plug it in.

 

$${\frac{{\frac{\left({\frac{{\frac{{\mathtt{x}}}{\left({\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}}\right)}}{\mathtt{\,\times\,}}\left({\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}}\right)}{\left({\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}}\right)}}\right)}{\left({\mathtt{1}}{\mathtt{\,-\,}}{\mathtt{x}}\right)}}}{\left({\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}}\right)}} = {\mathtt{0.233\: \!6}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\frac{{\sqrt{{\mathtt{\,-\,}}{\frac{{\mathtt{14\,508}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{6}}}}\right)}}{{\sqrt{{\mathtt{191\,844}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\small\textbf+\,}}{\mathtt{219\,876}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}{\mathtt{\,-\,}}{\mathtt{704\,375}}}}}}{\mathtt{\,-\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{704\,375}}}{\left({\mathtt{191\,844}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{502}}}{{\mathtt{219}}}}}}}{{\mathtt{2}}}}{\mathtt{\,-\,}}{\frac{{\sqrt{{\mathtt{191\,844}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\small\textbf+\,}}{\mathtt{219\,876}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}{\mathtt{\,-\,}}{\mathtt{704\,375}}}}}{\left({\mathtt{876}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{625}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6\,484\,410\,131}}}}}{\left({\mathtt{219}}{\mathtt{\,\times\,}}{{\mathtt{146}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{10\,930\,245\,625}}}{{\mathtt{84\,027\,672}}}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{6}}}}\right)}\right)}}{\mathtt{\,-\,}}{\mathtt{2}}\\

My goodness that looks horrible!

Let's see what the graph looks like and get the answer/s from there.

 

Alright there are your 2 answers.  I might keep going with the quadratic formula and get them that way.

$$x(2+x) = 0.2336(3+x)(1-x)\qquad \\\\
x^2+2x = 0.2336(3-3x+x-x^2)\qquad \\\\
x^2+2x = 0.2336(-x^2-2x+3)\qquad \\\\$$

I could just finish this by hand but I'mm goint to let the web 2 calc do it for me.

$${{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{0.233\: \!6}}{\mathtt{\,\times\,}}\left({\mathtt{\,-\,}}{{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right) \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\frac{\left({\sqrt{{\mathtt{103\,571}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{257}}\right)}{{\mathtt{257}}}}\\
{\mathtt{x}} = {\frac{\left({\sqrt{{\mathtt{103\,571}}}}{\mathtt{\,-\,}}{\mathtt{257}}\right)}{{\mathtt{257}}}}\\
\end{array} \right\} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = -{\mathtt{2.252\: \!235\: \!355\: \!360\: \!168\: \!6}}\\
{\mathtt{x}} = {\mathtt{0.252\: \!235\: \!355\: \!360\: \!168\: \!6}}\\
\end{array} \right\}$$

There you go, that is better!

These 2 answers would have been included in the original calculator ouput but some other imaginary roots were included as well.  You probably do not need to worry about those.

x(2+x) = 0.2336(3+x)(1-x)\qquad \\\\$$

 

you can keep going from here and solve it with the quadratic formula or you can just plug your initial equation into the site calc and get it to do it all for you.  

(x/(3+x) * (2+x)/(3+x) ) / (1-x)/(3+x) = 0.2336  

change the square brackets to round ones and change your decimal comma to a decimal point and just plug it in.

My goodness that looks horrible!

Let's see what the graph looks like and get the answer/s from there.

 

Alright there are your 2 answers.  I might keep going with the quadratic formula and get them that way.

$$x(2+x) = 0.2336(3+x)(1-x)\qquad \\\\
x^2+2x = 0.2336(3-3x+x-x^2)\qquad \\\\
x^2+2x = 0.2336(-x^2-2x+3)\qquad \\\\$$

I could just finish this by hand but I'mm goint to let the web 2 calc do it for me.

$${{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{0.233\: \!6}}{\mathtt{\,\times\,}}\left({\mathtt{\,-\,}}{{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right) \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\frac{\left({\sqrt{{\mathtt{103\,571}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{257}}\right)}{{\mathtt{257}}}}\\
{\mathtt{x}} = {\frac{\left({\sqrt{{\mathtt{103\,571}}}}{\mathtt{\,-\,}}{\mathtt{257}}\right)}{{\mathtt{257}}}}\\
\end{array} \right\} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = -{\mathtt{2.252\: \!235\: \!355\: \!360\: \!168\: \!6}}\\
{\mathtt{x}} = {\mathtt{0.252\: \!235\: \!355\: \!360\: \!168\: \!6}}\\
\end{array} \right\}$$

There you go, that is better!

These 2 answers would have been included in the original calculator ouput but some other imaginary roots were included as well.  You probably do not need to worry about those.

WolframAlpha gets a slightly different result from Melody's answer...I suspect the reason is in the way that WA is interpreting the multiple divisions of the two functions outside the brackets....

(The only change I made to the original problem was to subtract .2336 from both sides....)

 

Whatever.....I think the point here is that this one would be a tough one to evaluate by hand.......Based on the original form of the problem, it would be difficult to intuit how many "real' and/or "non-real" solutions there might be......
