\n" ); document.write( "\n" ); document.write( " $\"%28x-1%29%28x%5E2-2x-3%29\"$ Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x%28x%5E2-2x-3%29-1%28x%5E2-2x-3%29\"$ Expand.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

Distribute.\r

\n" ); document.write( "\n" ); document.write( " $\"x%5E3-2%2Ax%5E2-3%2Ax-x%5E2%2B2%2Ax%2B3\"$ Multiply.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x%5E3-3%2Ax%5E2-x%2B3\"$ Now combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"%28x-1%29%28x%5E2-2x-3%29\"$ expands to $\"x%5E3-3%2Ax%5E2-x%2B3\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, $\"%28x-1%29%28x%5E2-2x-3%29=x%5E3-3x%5E2-x%2B3\"$ .
\n" ); document.write( " \n" ); document.write( "
