\n" ); document.write( "\n" ); document.write( "\"%283h-5%29%283h%2B5%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( "\n" ); document.write( "\"%28highlight%283h%29-5%29%28highlight%283h%29%2B5%29\" Multiply the First terms:\"%283%2Ah%29%2A%283%2Ah%29=9%2Ah%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28highlight%283h%29-5%29%283h%2Bhighlight%285%29%29\" Multiply the Outer terms:\"%283%2Ah%29%2A%285%29=15%2Ah\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283h%2Bhighlight%28-5%29%29%28highlight%283h%29%2B5%29\" Multiply the Inner terms:\"%28-5%29%2A%283%2Ah%29=-15%2Ah\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283h%2Bhighlight%28-5%29%29%283h%2Bhighlight%285%29%29\" Multiply the Last terms:\"%28-5%29%2A%285%29=-25\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "---------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"9%2Ah%5E2%2B15%2Ah-15%2Ah-25\" Now collect every term to make a single expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"9%2Ah%5E2-25\" Now combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%283h-5%29%283h%2B5%29\" FOILs to \"9%2Ah%5E2-25\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"%283h-5%29%283h%2B5%29=9%2Ah%5E2-25\".\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
