Look at the left hand side of the equation. This is a difference of two squares. Factor it.

(x + y)(x – y) = x + y

Now we can divide both sides by (x + y) Note: we could not do this if x = -y because then we would be dividing by 0.

Now we get

(x – y) = 1

Hope that helped.

Before even solve this question,

0 came to my mind as a perfect answer. But one of the condition is X <> Y so x and y couldn’t equal to 0 at the same time.

So I simpled this:

x^2 – y^2 = x + y

x^2 – x = y^2 + y

-x – y = y^2 – x^2

-x – y + 2x = y^2 – x^2 +2x (plus 2x on each side)

x – y = y^2 – x^2 + 2x
