Question

FCATOR EACH POLYNOMIAL. LOOK FOR A GCF FIRST.

3x²-3y²​

Answer 1

3 (x + y) (x - y)

Explanation:

3x²-3y²​

GCF is 3

3(x² - y²)

Since both terms are perfect squares, factor using the difference of squares formula, a² − b² = (a+b) (a−b) where a = x and b = y.

So, the answer is 3 (x + y) (x - y)
