On the daily quiz to day many of us forgot how to factor out problems like...
(x+3)^3. All you do to solve these problems is set up the problem so it looks like (x+3) (x+3) (x+3), next you factor the first (x+3) in to the second (x+3) giving you (x+3) (x^2+6x+9). Than distribute the last (x+3) throughout.
x^3+6x^2+9x+3x^2+18x+27
combine like terms and your answer is...
x^3+9x^2+27x+27
