(x + 2y)(x – 2y)
This is a difference of squares, so we can use the formula:
(a + b)(a - b) = a^2 - b^2
In this case, we have:
(x + 2y)(x - 2y) = x^2 - (2y)^2 = x^2 - 4y^2
So the final answer is:
x^2 - 4y^2
(a + b)(a - b) = a^2 - b^2
In this case, we have:
(x + 2y)(x - 2y) = x^2 - (2y)^2 = x^2 - 4y^2
So the final answer is:
x^2 - 4y^2
