9x^{2}-12x+4=9x^{2}-12x+4
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(3x-2\right)^{2}.
9x^{2}-12x+4-9x^{2}=-12x+4
Subtract 9x^{2} from both sides.
-12x+4=-12x+4
Combine 9x^{2} and -9x^{2} to get 0.
-12x+4+12x=4
Add 12x to both sides.
4=4
Combine -12x and 12x to get 0.
\text{true}
Compare 4 and 4.
x\in \mathrm{C}
This is true for any x.
