On the question below, Bob Pursley said it was correct, however, I just wanted to make sure that it's not supposed to have another x value since it has x^2 in it.
Solve the inequality:
(2x-3)(4x)+x^2=>(3x+4)^2
I did 2x-3*4x
9x^2-12x on the left side
on the right side:
9x^2+24x+16
I substracted everything on the right side over to the left and made it => zero
9x^2-12x-9x^2-24x-16=>0
-36x-16=>0
x=<4/-9
I'm not sure if this is right or if I made an error somewhere.
