I don't understand the second part of your question.

Nataliya D. was correct on the first one. I didn't factor out the 9 first.
The correct answer was 9(x-2) (x+2).
The correct answer was 9(x-2) (x+2).
9x^2-36 = (3x+6) (3x-6) = 3(x+2)(3)(x-2) = 9(x-2)(x+2)
Or the best way 9(x^2-4) = 9(x-2)(x+2).
My apologies that in my haste I didn't COMPLETELY factor the expression.
