1. The problem statement, all variables and given/known data f(x) = (2x)(x-5)^(3) + 3x^2(x-5)^(2) Need to simplify. 2. Relevant equations 3. The attempt at a solution I tried simplifying completely but my answer wasn't even close. The Back of the book has: 5x(x-5)^(2)(x-2) I know its easy, but I'm drawing a blank...can anyone start me off on the right path to find how they got that answer?
