Question

Hi! I was wondering if someone could help me solve ((a^2)/(a-b))+((b^2)/(b-a))

Answer 1

I know I need a common denominator

Answer 2

denominator = (a-b)(b-a)

Answer 3

a-b is the opposite of b-a, try it with numbers

Answer 4

So I would multiply a2 by (b-a) and b2 with (a-b)?

Answer 5

...so you have a common denominator if you multiply one of them by -1

Answer 6

a^2/(a-b) - b^2/(a-b)

Answer 7

yes marie

Answer 8

(a^2 - b^2)/(a-b)

Answer 9

...then difference of squares

Answer 10

... in the numerator

Answer 11

...cancels with denominator

Answer 12

...leaving...

Answer 13

I see it now!
