Question

Factorise the expression x²-y²

Answer 1

(x + y)(x - y)

Explanation:

The expression x² - y² can be factorized using the difference of squares formula, which states that a² - b² = (a + b)(a - b). In your case, a = x and b = y. So, applying this formula, we have:

x² - y² = (x + y)(x - y)

So, the factorization of the expression x² - y² is (x + y)(x - y).
