$\"f%28x%29=a%28x%2B1%29%28x-5%29\"$
\n" ); document.write( "Use the point,
\n" ); document.write( " $\"1=a%281%2B1%29%281-5%29\"$
\n" ); document.write( " $\"1=a%282%29%28-4%29\"$
\n" ); document.write( " $\"1=-8a\"$
\n" ); document.write( " $\"a=-1%2F8\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"f%28x%29=-%281%2F8%29%28x%2B1%29%28x-5%29\"$
