Question

x² – y² is equal to ______.

Options

• (x – y) (х – y)

• (x + y) (x + y)

• (x – y) (x + y)

• (x – 2y) (2x – y)

Answer 1

x² – y² is equal to (x – y) (x + y).

Explanation:

The expression x² – y² is a difference of squares, which can be factorized using the formula:

a² – b² = (a – b)(a + b)

Here, (a = x) and (b = y).

So, x² – y² = (x – y)(x + y).
