    I. 3x2 + 22 x + 24 = 0,

    II. 3y2 – 10y + 3 = 0

    If x > y

    Incorrect Answer

    If x < y

    Correct Answer

    If x ≥ y

    Incorrect Answer

    If x ≤ y

    Incorrect Answer
    Explanation:

    3x2 + 22 x + 24 = 0
    3x2 + 18x + 4x + 24 = 0
    So x = -4/3, -6
    3y2 – 10y + 3 = 0
    3y2 – 9y – y + 3 = 0
    So y = 1/3, 3
    Put on number line
    -6… -4/3… 1/3… 3
