In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answers. I. x² - 7x - 60 = 0 II. y² + 13y + 40 = 0

x ≥ y
x ≤ y
x > y
x < y

Correct answer: x ≥ y

Solution

x=12 or -5. y=-8 or -5. Comparing all pairs: (12,-8)→x>y; (12,-5)→x>y; (-5,-8)→x>y; (-5,-5)→x=y. In all cases x≥y.
