\n" ); document.write( "\n" ); document.write( "\"%283x%2B7%29%28x-5%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%283x%29%2B7%29%28highlight%28x%29-5%29\" Multiply the First terms:\"%283%2Ax%29%2A%28x%29=3%2Ax%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28highlight%283x%29%2B7%29%28x%2Bhighlight%28-5%29%29\" Multiply the Outer terms:\"%283%2Ax%29%2A%28-5%29=-15%2Ax\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283x%2Bhighlight%287%29%29%28highlight%28x%29-5%29\" Multiply the Inner terms:\"%287%29%2A%28x%29=7%2Ax\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283x%2Bhighlight%287%29%29%28x%2Bhighlight%28-5%29%29\" Multiply the Last terms:\"%287%29%2A%28-5%29=-35\".\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: \"3%2Ax%5E2\", \"-15%2Ax\", \"7%2Ax\", \"-35\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%2Ax%5E2-15%2Ax%2B7%2Ax-35\" Now add every term listed above to make a single expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%2Ax%5E2-8%2Ax-35\" Now combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%283x%2B7%29%28x-5%29\" FOILs to \"3%2Ax%5E2-8%2Ax-35\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"%283x%2B7%29%28x-5%29=3%2Ax%5E2-8%2Ax-35\".
\n" ); document.write( "
\n" ); document.write( "
