    Question

    Factor the polynomial: x³ - 6x² + 11x -

    6.
    A (x - 1)(x - 2)(x - 3) Correct Answer Incorrect Answer
    B (x + 1)(x + 2)(x + 3) Correct Answer Incorrect Answer
    C (x - 2)(x - 3)(x - 1) Correct Answer Incorrect Answer
    D (x - 1)(x + 2)(x - 3) Correct Answer Incorrect Answer

    Solution

    Using synthetic division to find roots, we test possible rational roots. Testing x = 1: 1³ - 6(1)² + 11(1) - 6 = 0. Thus, (x - 1) is a factor. Dividing x³ - 6x² + 11x - 6 by (x - 1): The result is x² - 5x + 6 = (x - 2)(x - 3). So, the complete factorization is (x - 1)(x - 2)(x - 3). Correct Answer: a) (x - 1)(x - 2)(x - 3).
