Question

I. 2y² - 35y + 132 = 0

II. 2x² - 31x + 110 = 0

A if x>y Correct Answer Incorrect Answer
B if x≥y Correct Answer Incorrect Answer
C if x Correct Answer Incorrect Answer
D if x≤y Correct Answer Incorrect Answer
E if x=y or the relationship cannot be established Correct Answer Incorrect Answer

Solution

I. 2y² - 35y + 132 = 0 2y² - 11y - 24 y + 132 = 0 y (2 y – 11) - 12 (2 y – 11) = 0 y = 12, 11/2 II. 2x² - 31x + 110 = 0 2x² - 20 x - 11 x + 110 = 0 2x(x – 10) – 11(x – 10) = 0 x = 10, 11/2 Hence, relationship cannot be established between x and y.
