For the first question try setting it up this way: (1  1/a) / (1  1/a^2) = (a  1)/a / (a^2  1) / a^2 Instead of dividing, multiply by the reciprocal, then rewrite a^2  1 as (a + 1)(a  1). You will find that most everything cancels. As for the second question, try multiplying everything by x^2. That way you will get 3x  2x^2 + 8  4x^2 = x^2
