Hello, Having trouble with this one...
Solve the inequality:
(2x3)(4x)+x^2=>(3x+4)^2
I did 2x3*4x
9x^212x 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^212x9x^224x16=>0
36x16=>0
x=<4/9
I'm not sure if this is right or if I made an error somewhere.
