Homework Help: Math

Posted by muffy on Saturday, September 12, 2009 at 1:32pm.

Hello, Having trouble with this one...

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.
