This is a multiplication of fractions problem, so I guess you know you need to factor each of these numerators and denominators:


I'm sorry but in this format, I don't know how to show the factors all dividing out, but the way I did it on paper, all the factors divide out, except the factor of %282y-1%29 in the second numerator and the %282y-3%29 in the third denominator. So the final answer is
%282y-1%29%2F%282y-3%29+
