Question

simplify x^2-y^2
y - x

Answer 1

I don't understand the way you're posting these: what is the y - x on the bottom? Is that the denominator?

Answer 2

yeah y-x is on the bottom is is set up like a division problem

Answer 3

(x + y)(x - y)
-----------
(y - x)

(x + y)(x - y)
-----------
-(x - y) you can flip terms around a negative sign if you put a - out front

(x + y)
------ (x - y)'s cancel
-1

-(x + y) the negative one can go on top

-x - y distribute.. either this answer or the one above it is good.
