- Problem 2: $x^2 + 2x - 3 = (x + 3)(x - 1)$ → Match with letter A (assuming A corresponds to $(x - 1)$ or $(x + 3)$ based on the answer key layout).
- Problem 3: $x^2 + 11x + 18 = (x + 2)(x + 9)$ → Match with letter B (assuming B corresponds to $(x + 2)$ or $(x + 9)$).
- Problem 7: $x^2 - 11x - 12 = (x - 12)(x + 1)$ → Match with letter C (assuming C corresponds to $(x - 6)$ is incorrect; likely a mislabel — correct factor is $(x - 12)$ or $(x + 1)$, so match with available letter for those).
- Problem 8: $x^2 - x - 30 = (x - 6)(x + 5)$ → Match with letter C (since $(x - 6)$ is listed under C).
