I. 3x² + 22 x + 24 = 0

II. 2y² + 11y + 12 = 0

x > y

x < y

x ≤ y

x = y or relation cannot be established

Explanation:

3x² + 22 x + 24 = 0
3x² + 18x + 4x + 24 = 0
Gives x = -4/3, -6
2y² + 11y + 12 = 0
2y² + 8y + 3y + 12 = 0
Gives y = -4, -3/2
Put all values on number line and analyze the relationship
-6…..-4…. -3/2….-4/3
