\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"r%28r%5E2-rp%2Bp%5E2%29%2Bp%28r%5E2-rp%2Bp%5E2%29\" Expand the expression. Remember something like \"%28a%2Bb%29%28c%2Bd%2Be%29\" expands to \"a%28c%2Bd%2Be%29%2Bb%28c%2Bd%2Be%29\"\r

\n" ); document.write( "\n" ); document.write( "In other words, \"%28r%2Bp%29%28r%5E2-rp%2Bp%5E2%29=r%5E3%2Bp%5E3\"\r
