Factor:
11x%5E2%2B11xy%2B13x%2B13y Group the terms as follows:
%2811x%5E2%2B11xy%29%2B%2813x%2B13y%29 From the first group, factor 11x and from the second group, factor 13.
11x%28x%2By%29%2B13%28x%2By%29 Now factor the common factor of (x+y).
%28x%2By%29%2811x%2B13%29 This is called "factoring by grouping"
