Notice that:
\n" ); document.write( " $\"x%5E2y%5E2-256\"$
\n" ); document.write( ".
\n" ); document.write( "can be written as:
\n" ); document.write( " $\"%28xy%29%5E2+-+16%5E2\"$
\n" ); document.write( ".
\n" ); document.write( "This is a \"difference of squares\", a special case in factoring:
\n" ); document.write( " $\"%28xy+-+16%29%28xy+%2B+16%29\"$
\n" ); document.write( " \n" ); document.write( "
