1. The problem statement, all variables and given/known data I have the answer but I don't understand how they got it. What did they expand? These are the last two in the book but I cant understand how they cancelled the denominator. 2. Equations Equation 1: f(x) = (x3+8)/(x+2) Equation 2: f(x) = (x3-27)/(x-3) The answers are: x2-2x+4 x2+3x+9 Thanks :).
