    Question

    In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer if;

    I. 64x2 - 64x + 15  = 0      II.

    21y2 - 13y + 2  =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 Correct Answer Incorrect Answer

    Solution

    I. 64x - 64x + 15  = 0  64x - 24x - 40x + 15 = 0  8x (8x - 3 ) - 5 ( 8x - 3 ) = 0 (8x - 5 ) ( 8x - 3) = 0 x = `(3)/(8)`  , `(5)/(8)` II. 21y2 - 13y + 2  =0     21y2 - 7y - 6y + 2 = 0     7y ( 3y - 1 ) -2 ( 3y - 1 ) = 0     y = `(2)/(7)`  , `(1)/(3)` Hence, x > y
