quadratic

Re-write as   x^2 + 10x = 0

                        x(x+10) = 0        x = 0   or  -10        

Hey there, Guest!

 

$x^2+10x+25=8+17$

 

Step 1: Simplify both sides of the equation.

$x^2+10x+25=25$

 

Step 2: Subtract 25 from both sides.

$x^2+10x+25−25=25−25$

$x^2+10x=0$

 

Step 3: Factor the left side of the equation.

$x(x+10)=0$

 

Step 4: Set factors equal to 0.

$x=0$ or $x+10=0$

 

x=0 or x=−10

 

Therefore your answer is -10.

 

Hope this helped! :)
