In the given question, two equations numbered l and II are given. You have to solve both the equations and mark the appropriate answer-I. 2x2 + 6x – 80 = 0II. 3y2 + 12y + 9 = 01. x > y2. x  ≥ y 3. x < y4. x ≤ y5. x = y or the relation cannot be established

Answer» Correct Answer - Option 5 : x = y or the relation cannot be established

Equation I:

2x2 + 6x – 80 = 0

⇒ 2x2 – 10x + 16x – 80   = 0

⇒ (2x + 16) (x – 5) = 0

⇒ x = - 8 or x = 5

Equation II:

3y2 + 12y + 9 = 0

⇒ 3y2 + 3y + 9y + 9 = 0

⇒ (3y + 9) (y + 1) = 0

⇒ y = - 3 or y = - 1

Comparing the values of x and y,

x = y or the relation cannot be established
