Think \"difference of squares\":
\n" ); document.write( " $\"x%5E2-49\"$
\n" ); document.write( "Can be rewritten as:
\n" ); document.write( " $\"x%5E2-7%5E2\"$
\n" ); document.write( "Because it is now a \"difference of squares\" we can factor as:
\n" ); document.write( " $\"%28x-7%29%28x%2B7%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
