I. x2– 19x + 84 = 0
II. y2– 25y + 126 = 0
In the following question, one or two equation(s) is/are given. You have to solve both the equations and find the relation between ‘x’ and ‘y’ and mark correct answer. I. x2– 19x + 84 = 0 II. y2– 25y + 126 = 0

If x ≥ yগ)
If x < yঘ)
If x ≤ yঙ)
If x = y or the relation cannot be determinedExplanation
We will solve both the equations separately. Equation I: x 2 – 19x + 84 = 0 ⇒ x 2 – 12x – 7x + 84 = 0 ⇒ (x – 12) (x – 7) = 0 ⇒ x = 12 or x = 7 Equation II: y 2 – 25y + 126 = 0 ⇒ y 2 – 18y – 7y + 126 = 0 ⇒ (y – 18) (y – 7) = 0 ⇒ y = 18 or y = 7 So, the relation cannot be determinedRelated questions
