Factor by grouping:
\n" ); document.write( " $\"9m%5E3%2B4mn-9m%5E2-4n\"$ Group the terms as shown:
\n" ); document.write( " $\"%289m%5E3%2B4mn%29-%289m%5E2%2B4n%29\"$ Factor $\"m\"$ from the first group.
\n" ); document.write( " $\"m%289m%5E2%2B4n%29-%289m%5E2%2B4n%29\"$ Now factor the common factor $\"%289m%5E2%2B4n%29\"$ from each term:
\n" ); document.write( " $\"highlight%28%289m%5E2%2B4n%29%28m-1%29%29\"$ ...and there it is! \n" ); document.write( "

\n" );
