If a does not equal b, what is the value of a+b?
1) (a^2-b^2) / (a-b) = 6
2) (a+b)^2 = 36
I understand that 2 is definetly not possible because we get a+b = plus or minus 6
but anyways.. the answer is A
Is there anyway someone can please explain why this is true? I thought the answer was C
Thanks in advance
