Can you help me with this?

2   2
M + N     M + N     2M
----- +  ------- - ------ =
2   2
N - M     N - M     M - N

Thanks a lot!

Hi there Emmanuel!

For this problem you need a common denominator.

I'd suggest using N^2 - M^2  (that is, N squared minus M squared)
as the common denominator.

(N - M) times (N + M) will give you N^2 - M^2

So will (M - N) * (-1) * (N + M)

Can you take it from here?

Write us back if you need more help.
