\n" ); document.write( "\n" ); document.write( " $\"%283x-4y%29%28x%5E2-2xy%2B5y%5E3%29\"$ Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"3x%28x%5E2-2xy%2B5y%5E3%29-4y%28x%5E2-2xy%2B5y%5E3%29\"$ Expand.\r
\n" ); document.write( "
\n" ); document.write( "

Distribute.\r

\n" ); document.write( "\n" ); document.write( " $\"3x%5E3-6x%5E2y%2B15xy%5E3-4x%5E2y%2B8y%5E2x-20y%5E4\"$ Multiply.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"3x%5E3-10x%5E2y%2B15xy%5E3%2B8y%5E2x-20y%5E4\"$ Now combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"%283x-4y%29%28x%5E2-2xy%2B5y%5E3%29\"$ expands to $\"3x%5E3-10x%5E2y%2B15xy%5E3%2B8y%5E2x-20y%5E4\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, $\"%283x-4y%29%28x%5E2-2xy%2B5y%5E3%29=3x%5E3-10x%5E2y%2B15xy%5E3%2B8y%5E2x-20y%5E4\"$ .
