Difference of two squares will also come in handy.
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?
I think I am following what you are saying, not 100% sure it is correct. Spoiler:
why the at the end?
oh yeah i completely forgot about that, i though they'd just cancel each other out
