Which of the following is the expansion of (2x – y) 2?

4x² - 4xy + y²

Step-by-step explanation:

For clarity it is essential that you use (2x - y)^2 or (2x – y)² to indicate the square of (2x - y).

Since we're squaring (2x - y), we expect 3 terms in the expansion.

(2x - y)(2x - y) = 4x^2 - 4xy + y^2, or 4x² - 4xy + y²

Next time you see "the following," please share the answer choices.  Thank you.

4x and 6y

im not sure though

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
