Question

    In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer.

    I. 5x² -14x + 8 = 0    II. 2y² + 17y  + 36 =

    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. . 5x² -14  x + 8 = 0     5x² - 10x - 4x + 8 = 0     5x(x-2) - 4 (5x – 2) (x -2 ) (5x-4) x = 2, 4/5 II. 2y ²  - 17y   + 36 = 0       2y ² + 9y + 8y + 36 = 0     y (  y + 9) + 4( y  + 9) (y  + 4) (2y + 9) y  =  - 4, -9/2  Hence, x > y
