\r
\n" ); document.write( "\n" ); document.write( " $\"9x%5E2%2B8x-7\"$ Start with the given polynomial.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"9%28-3%29%5E2%2B8%28-3%29-7\"$ Plug in $\"x=-3\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"9%289%29%2B8%28-3%29-7\"$ Square $\"-3\"$ to get $\"9\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"81%2B8%28-3%29-7\"$ Multiply $\"9\"$ and $\"9\"$ to get $\"81\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"81-24-7\"$ Multiply $\"8\"$ and $\"-3\"$ to get $\"-24\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"50\"$ Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"9x%5E2%2B8x-7=50\"$ when $\"x=-3\"$
\n" ); document.write( " \n" ); document.write( "
