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

anonymous · Answer

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

(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.
