so for the top part,

*(a-b) = m*and*(a+b)*would be*n*, so you would get(a-b)(a+b)/x^b^2

which would give you

so would the answer be x^a^2 because there would be 2 x^b^2, both in the divisor and divident, so it would cancel it out? - September 16th 2009, 02:56 PMpickslides
I think I am following what you are saying, not 100% sure it is correct.
