\n" ); document.write( "\n" ); document.write( " $\"%287m%2B9%29%288m%5E2%2Bm%2B7%29\"$ Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"7m%288m%5E2%2Bm%2B7%29%2B9%288m%5E2%2Bm%2B7%29\"$ Expand.\r
\n" ); document.write( "
\n" ); document.write( "

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"56m%5E3%2B79m%5E2%2B58m%2B63\"$ Now combine like terms.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " So $\"%287m%2B9%29%288m%5E2%2Bm%2B7%29\"$ expands to $\"56m%5E3%2B79m%5E2%2B58m%2B63\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, $\"%287m%2B9%29%288m%5E2%2Bm%2B7%29=56m%5E3%2B79m%5E2%2B58m%2B63\"$ .
