Answer:
B.(x-y)(x+y)
Step-by-step explanation:
The factor of x² - y² can be represented by,
A.(x - y)²
INCORRECT:
Translated to (x - y)(x - y) as the exponent says it multiplied by it self
(x - y)(x - y) = x²- 2xy + y² which doesn't match
B.(x-y)(x+y)
Correct!
x times x = x²
-y times y = -y²
x² - y²
C.(x+y)(x+y)
INCORRECT
x times x = x²
y times y = y²
x² + y² which doesn't match as y positive here
D.2(x - y)
INCORRECT
distribute 2 so 2x - 2y which isn't the original
