Question

    I. x² + 11x + 24 = 0 II. y² + 17y + 72 =

    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 x = y or Relationship between x & y cannot be established Correct Answer Incorrect Answer

    Solution

    I. x² + 11x + 24 = 0  x² + 3x + 8 x + 24 = 0  x (x + 3) + 8 (x + 3) = 0 x = - 3, - 8 II. y² + 17y + 72 = 0 y² + 8y + 9 y + 72 = 0 y (y + 8) + 9 (y + 8) = 0 (y + 8) (y + 9) = 0 y = - 8, - 9 Hence, x≥y
