Directions (): Following question contains two equations as I and II. You have to solve both equations and determine the relationship between them and give answer as,

I) x² – 7x + 10 = 0

II) y² + 8y + 15 = 0

x> y

x ≥ y

x = y or relationship can’t be determined.

x< y

x ≤ y

Explanation:

x² – 7x + 10 = 0
x² – 5x – 2x + 10 = 0
x(x – 5) – 2(x – 5) = 0
x = 5, 2
y² + 8y + 15 = 0
y² + 5y + 3y + 15 = 0
y(y + 5) + 3(y + 5) = 0
y = -3, -5
x>y
