    Question

    What will be the greatest common divisor (GCD) of (x²

    - 12x + 35) and (x² - 9x + 14).
    A x - 2 Correct Answer Incorrect Answer
    B x - 5 Correct Answer Incorrect Answer
    C x - 3 Correct Answer Incorrect Answer
    D x - 7 Correct Answer Incorrect Answer

    Solution

    (x² - 12x + 35) = x² - 7x - 5x + 35 = x(x - 7) - 5(x - 7) = (x - 7)(x - 5) x² - 9x + 14 = x² - 7x - 2x + 14 = x(x - 7) - 2(x - 7) = (x - 7)(x - 2) So, required GCD = (x - 7) Hence, option d.
