How to solve this equation?

32x+3x2=0

 

32x+3x2=03(2x)+3x=23(2x)=23x

2x×ln 3=ln (23x)

?

Excuse me!

This requires a numerical solution method.  Draw a graph first to see where the solution(s) might lie.

Agree with asinus....graphical method is easiest....here is my result from desmos calculator:

Humm ... I might need to slow down on the fermented bananas, I didn’t notice any mention of a graphical method by Asinus. 

 

The graphical method may be the easiest when you are using a computerized graphing tool that iterates the value of (x) over a range that includes y=0.   

Do it with graphing paper; calculate each plotted point with a calculator (or a slide rule) and then explain how it’s easier.indecision

Hi Ginger,

Graphing it  is easier because than asinus's method becasue asinus never got an answer.

He just re-arranged it a little and then realized that he didn't know how to solve it.
