You can put this solution on YOUR website!
I'm assuming you need it factored.
\n" ); document.write( "r^2-49
\n" ); document.write( ".
\n" ); document.write( "Can be rewritten as:
\n" ); document.write( "r^2-7^2
\n" ); document.write( "Now, it is a \"difference of squares\"
\n" ); document.write( "which factors out as:
\n" ); document.write( "(r+7)(r-7) \n" ); document.write( "

\n" );
