First separate out all common terms:
\n" ); document.write( " $\"x%5E3y%28x%5E2y%5E2-9xy%2B20%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Then factor the polynomial inside the ( ). To factor the polynomial, find two factors of 20 that add up to be -9. In this problem -4 + -5 = -9 and -4 * -5 = 20.
\n" ); document.write( " $\"x%5E3y%28xy+-+4%29%28xy+-+5%29\"$ \r
\n" ); document.write( "\n" ); document.write( "The three factors are $\"x%5E3y\"$ ; $\"xy-4\"$ ; and $\"xy-5\"$ . \n" ); document.write( "

\n" );
