Question

    I. 2x² - 15x  + 13 = 0

    II. 3y² - 6y + 3 = 0

    A If x ≥ y Correct Answer Incorrect Answer
    B If If x ≤ y Correct Answer Incorrect Answer
    C If If x > y Correct Answer Incorrect Answer
    D If x < y Correct Answer Incorrect Answer
    E If x = y or relationship between between x and y cannot be established Correct Answer Incorrect Answer

    Solution

    I. 2 x ² - 15 x  + 13=0 2 x ² - 2 x  - 13 x  + 13= 0 2 x  ( x  – 1) – 13 ( x – 1) (2 x  – 13) ( x  – 1) = 0 x = 1, 13/2 II. 3 y ² - 6 y  + 3 = 0  3 y ² - 3 y  - 3 y  + 3 = 0 3 y  ( y – 1) - 3 ( y  – 1) (3 y – 3) ( y – 1) = 0  y  = 1, 1   Hence,  x ≥ y
