I'm assuming you mean:
\n" ); document.write( " $\"%28121-x%5E2%29%2F%28x%5E2%2B15x%2B144%29\"$
\n" ); document.write( "This is factoring-
\n" ); document.write( " $\"%28%2811-x%29%2811%2Bx%29%29%2F%28%28x%2B11%29%28x%2B4%29%29\"$ Note-if you FOIL these back, you'll see you get the original polynomials.
\n" ); document.write( " $\"%2811-x%29%2F%28x%2B4%29\"$ The 11+x cancels with the x+11 \n" ); document.write( "

\n" );
