we can write it like this:
[tex] \frac{4*(3x)*(3x)}{(2x)(2x)} [/tex]
if x isn't 0, we can divide both sides by x:
[tex] \frac{4*(3x)*(3)}{(2x)(2)} [/tex]
and again
[tex] \frac{4*(3)*(3)}{(2)(2)} [/tex]
and now we can calcuate
[tex] \frac{4*9)}{4} [/tex]
and divide both sides by 4.
We're left with 9!!
so the solution is 9!
