$\"x%5E2%2Ak-y%5E2%2Ak\"$ Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"k%28x%5E2-y%5E2%29\"$ Factor out the GCF 'k'\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"k%28x%2By%29%28x-y%29\"$ Factor $\"x%5E2-y%5E2\"$ to get $\"%28x%2By%29%28x-y%29\"$ using the difference of squares formula.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"x%5E2%2Ak-y%5E2%2Ak=k%28x%2By%29%28x-y%29\"$ \n" ); document.write( "

\n" );
