To multiply, you just multiply the numerator by the numerator and the denominator by the denominator.
\n" ); document.write( "So you get (x^2+x-20)x/x^2(x+5).
\n" ); document.write( "Then you need to simplify. Factor the trinomial x^2+x-20.
\n" ); document.write( "x^2+x-20 = (x+5)(x-4)
\n" ); document.write( "Now substitute in those factors.
\n" ); document.write( "(x+5)(x-4)x/x^2(x+5)
\n" ); document.write( "Now cancel out factors in the numerator and denominator.
\n" ); document.write( "x+5 and x are the factors in the numerator and denominator.
\n" ); document.write( "(x-4)/x is the simplified product. \n" ); document.write( "

\n" );
