\"%28c-d%29r%5E3-%28c-d%29s%5E3\" Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let \"z=c-d\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"zr%5E3-zs%5E3\" Replace each \"c-d\" term with \"z\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"z%28r%5E3-s%5E3%29\" Factor out the GCF \"z\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"z%28r-s%29%28r%5E2%2Brs%2Bs%5E2%29\" Factor \"r%5E3-s%5E3\" by the difference of cubes formula. Note: let me know if you need help with this part.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28c-d%29%28r-s%29%28r%5E2%2Brs%2Bs%5E2%29\" Plug in \"z=c-d\"\r

\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%28c-d%29r%5E3-%28c-d%29s%5E3\" completely factors to \"%28c-d%29%28r-s%29%28r%5E2%2Brs%2Bs%5E2%29\"\r
