I got that A=-x-5 and B=x^2-10 Apparently either one of them or both are wrong.

(4/(x - 4)) - (2/(x + 4)) = (2x + 24)/[(x - 4)*(x + 4)] Note: x^2 - 16 = (x - 4)*(x + 4); Thus, 2x + 24 + (-3x - 3) = -x + 21 (Which is your "A") And then your B is the common denominator: (x - 4)*(x + 4); Thus, the final answer of A/B is: (-x + 21)/[(x - 4)*(x + 4)]
