I. 15x² – 29x + 12 = 0

II. 15y² – 22y + 8 = 0

x < y

x ≥ y

x ≤ y

x = y or relation cannot be established

Explanation:

15x² – 29x + 12 = 0
15x² – 9x – 20x + 12 = 0
Gives x = 3/5, 4/3
15y² – 22y + 8 = 0
15y² – 10y – 12y + 8 = 0
Gives y = 4/5, 2/3
Put all values on number line and analyze the relationship
3/5….. 2/3….. 4/5…. 4/3
