[QUOTE="noahsdev, post: 4542978, member: 485843"] [h2]Homework Statement [/h2] 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 can't understand how they canceled the denominator. [b]2. Equations [/b] Equation 1: f(x) = (x[SUP]3[/SUP]+8)/(x+2) Equation 2: f(x) = (x[SUP]3[/SUP]-27)/(x-3) The answers are: x[SUP]2[/SUP]-2x+4 x[SUP]2[/SUP]+3x+9 Thanks :). [/QUOTE]
