help math

Hey there, Guest!

So,  don't really understand what you mean by u and v, but hey, I can give you the solution to x.

Step 1: Subtract from both sides.

$3x^2+5x+7−(2x^2−4x−11)=2x^2−4x−11−(2x^2−4x−11)$

$x^2+9x+18=0$

Step 2: Factor

(x+3)(x+6)=0

Step 3:

x= -3, -6

Hope this helped! :)
