$\"27x%5E3%2B343y%5E3+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%283x%29%5E3%2B%287y%29%5E3+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%283x%2B7y%29%28%283x%29%5E2-%283x%29%287y%29%2B%287y%29%5E2%29+\"$ Sum of cubes factoring rule\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%283x%2B7y%29%289x%5E2-21xy%2B49y%5E2%29+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"27x%5E3%2B343y%5E3+\"$ factors to $\"%283x%2B7y%29%289x%5E2-21xy%2B49y%5E2%29+\"$ \n" ); document.write( "

\n" );
