Your classmate was asked to square (3x + 5), he answered 9x² – 25. Is his answer correct?

• Yes, because squaring a binomial always produces a binomial product.

• Yes, because product rule is correctly applied.

• No, because the answer must be 9x² + 25.

• No, because squaring a binomial always produces a perfect square trinomial
