\n" ); document.write( "\n" ); document.write( "\"%283-2x%29%283x%2B1%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%283%29-2x%29%28highlight%283x%29%2B1%29\" Multiply the First terms:\"%283%29%2A%283%2Ax%29=9%2Ax\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28highlight%283%29-2x%29%283x%2Bhighlight%281%29%29\" Multiply the Outer terms:\"%283%29%2A%281%29=3\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283%2Bhighlight%28-2x%29%29%28highlight%283x%29%2B1%29\" Multiply the Inner terms:\"%28-2%2Ax%29%2A%283%2Ax%29=-6%2Ax%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283%2Bhighlight%28-2x%29%29%283x%2Bhighlight%281%29%29\" Multiply the Last terms:\"%28-2%2Ax%29%2A%281%29=-2%2Ax\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "---------------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "So we have the terms: \"9%2Ax\", \"3\", \"-6%2Ax%5E2\", \"-2%2Ax\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"9%2Ax%2B3-6%2Ax%5E2-2%2Ax\" Now add every term listed above to make a single expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-6x%5E2%2B7x%2B3\" Now combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%283-2x%29%283x%2B1%29\" FOILs to \"-6x%5E2%2B7x%2B3\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"%283-2x%29%283x%2B1%29=-6x%5E2%2B7x%2B3\".
\n" ); document.write( "
\n" ); document.write( "
