Use the FOIL method:

FOIL = First, Outside, Inside, Last


(x + y)(x - y)


(x)(x) = x²

(x)(-y) = -xy

(y)(x) = xy

(y)(-y) = -y²


x² - xy + xy - y²


Simplify. Combine like terms


x² (-xy + xy) - y²


x² - y²


x² - y² is your answer


hope this helps

The answer to this problem is x² - y².


To solve this problem, we can use a factoring technique. In this problem, we see the factored form of the difference of two squares. The difference of two squares, and how they are factored, is:


x² - y² = (x + y)(x - y)


Since we are given the factored form, we must 'unfactor' it. Since the 'unfactored' form is x² - y², the answer to this problem is x² - y².
