    Question

    I. 2x² + 11x + 12 = 0 II. 2y² + 19y +

    45 = 0
    A if x>y Correct Answer Incorrect Answer
    B if x≥y Correct Answer Incorrect Answer
    C if x Correct Answer Incorrect Answer
    D if x≤y Correct Answer Incorrect Answer
    E if x=y or the relationship cannot be established. Correct Answer Incorrect Answer

    Solution

    I. 2x² + 11x + 12 = 0 2x² + 8x + 3x + 12 = 0 2x (x + 4) + 3 (x + 4) = 0 (2x + 3) (x + 4) = 0 x = - 4, -3/2 II. 2y² + 19y + 45 = 0 2y² + 10y + 9y + 45 = 0 2y (y + 5) + 9 (y + 5) = 0 y = - 5, - 9/2 Hence, x > y
