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