    Question

    I. 3x² + 17 x - 28 = 0 II. 3 y² -22 y +

    24 = 0
    A If x ≥ y Correct Answer Incorrect Answer
    B If x ≤ y Correct Answer Incorrect Answer
    C If x > y Correct Answer Incorrect Answer
    D If x < y Correct Answer Incorrect Answer
    E If relationship between a and b cannot be established or x = y Correct Answer Incorrect Answer

    Solution

    I. 3x² + 17 x - 28 = 0 3x² - 4 x + 21 x - 28 = 0 x (3 x – 4) + 7 (3 x – 4) = 0 x = - 7 , 4/3 II. 3 y² -22 y + 24 = 0 3 y² - 18 y - 4 y + 24 = 0 3 y(y – 6) – 4(y – 6) = 0 (3 y – 4) (y – 6) = 0 y = 6, 4/3 Hence, x≤y
