\n" ); document.write( "\n" ); document.write( "\"%287x%5E3%2B3%29%286x%5E5-2%29\" Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now let's FOIL the expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Remember, when you FOIL an expression, you follow this procedure:\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28highlight%287x%5E3%29%2B3%29%28highlight%286x%5E5%29-2%29\" Multiply the First terms:\"%287%2Ax%5E3%29%2A%286%2Ax%5E5%29=42%2Ax%5E8\".\r

\n" ); document.write( "\n" ); document.write( "\"%287x%5E3%2Bhighlight%283%29%29%28highlight%286x%5E5%29-2%29\" Multiply the Inner terms:\"%283%29%2A%286%2Ax%5E5%29=18%2Ax%5E5\".\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"42%2Ax%5E8-14%2Ax%5E3%2B18%2Ax%5E5-6\" Now collect every term to make a single expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%287x%5E3%2B3%29%286x%5E5-2%29\" FOILs to \"42%2Ax%5E8-14%2Ax%5E3%2B18%2Ax%5E5-6\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"%287x%5E3%2B3%29%286x%5E5-2%29=42%2Ax%5E8-14%2Ax%5E3%2B18%2Ax%5E5-6\".\r
