    Question

    I. x2ย - 9x - 52 = 0 II.

    y2ย - 16y + 63 = 0 In each of the following questions, there are two equations. You have to solve both equations and mark the correct answer.
    A if x>y Correct Answer Incorrect Answer
    B if x Correct Answer Incorrect Answer
    C if xโ‰ฅy Correct Answer Incorrect Answer
    D if x=y or relationship cannot be established. Correct Answer Incorrect Answer

    Solution

    I. x2ย - 9x - 52 = 0 => x2ย - 13x + 4x - 52 = 0 => x(x - 13) + 4(x - 13) = 0 => (x - 13) (x + 4) = 0 => x = 13, -4 II. y2ย - 16y + 63 = 0 => y2ย - 9y - 7y + 63 = 0 => y(y - 9) - 7(y - 9) = 0 => (y - 9) (y - 7) = 0 => y = 9, 7 Hence, the relationship cannot be established between x and y.
