I. 3x² + 14x – 5 = 0

II. 4y² + 5y – 6 = 0

x < y

x ≥ y

x ≤ y

x = y or relation cannot be established

Explanation:

3x² + 14x – 5 = 0
3x² + 15x – x – 5 = 0
Gives x = -5, 1/3
4y² + 5y – 6 = 0
4y² + 5y – 6 = 0
Gives y = -2, 3/4
Put all values on number line and analyze the relationship
-5….-2….. 1/3…. 3/4
