1. Factor completely:
x%5E3y-3x%5E2y-10xy First factor xy
xy%28x%5E2-3x-10%29 Now factor the parentheses.
xy%28x-5%29%28x%2B2%29
2. Factor completely:
x%5E2-4xy%2B12ax-48ay Factor by grouping as shown:
%28x%5E2-4xy%29+%2B+%2812ax-48ay%29 Factor x from the first group and 12a from the second group.
x%28x-4y%29+%2B+12a%28x-4y%29 Now factor the (x-4y).
%28x-4y%29%28x%2B12a%29
3. Factor completely:
x%5E2-5x-6
%28x-6%29%28x%2B1%29
4. Factor completely:
36x%5E2-4y%5E2 This is the difference of two squares:
%286x-2y%29%286x%2B2y%29
5. Factor completely:
9x%5E2%2B40x%2B16
%289x%2B4%29%28x%2B4%29
6. Factor completely:
3x%5E2-30x%2B48 First factor 3.
3%28x%5E3-10x%2B16%29 Now factor the parentheses.
3%28x-2%29%28x-8%29
