Question

(x + y)(x - y)
___________
(x + y) to the power of 2

Answer 1

(x+y) to the power of 2 = (x+y)*(x+y) yes?
then a (x+y) from the top and bottom can cancel out so you are left with (x-y) over (x+y)

Answer 2

so, ypu basically expand it and you get a (x-y)
but i thought you would cancle out the bottom one and the answer would just be (x-y)

Answer 3

but (x+y) to the power of 2 = (x+y)*(x+y)
meaning that there are two (x+y)'s multiplied by each other.
and the top (x+y) only cancel's out one of the bottom ones.

Answer 4

oh yeah i forgot that it was to the power of 2
thank you by the way i understand now

Answer 5
