Question

I. 2 x ² + x  – 1 = 0                 

II. 2 y ² - 3 y + 1 = 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 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 + x  – 1 = 0 (x – 1) (2 x + 1) = 0 x  = 1, - 1/2 II. 2 y ² - 3 y  + 1 = 0 (2 y  – 1) ( y – 1) = 0 y = 1, 1/2 Hence,  x ≤ y
