Alyn was tasked to factor out the expression 8a³ + 27z³ and her answer is (4a + 9z)(4a² - 6az + 9z²). Is she correct?

• Yes, because the factors are correct.

• Yes, because it follows the general rule (x + y)(x² - xy + y²) .

• No, because the cube root is not correct.

• No, because it does not follows the general rule (x + y)(x² - xy + y²)
