Multiple choice

In the following questions two equations I and II are given. You have to solve both the equations and give answer. $(I) (x^2 + 4x - 21 = 0)$ $(II) (y^2 + 2y - 35 = 0)$

  1. If x < y

  2. If x > y

  3. If x ≤ y

  4. If x ≥ y

  5. If x = y or the relationship cannot be determined

E Correct answer
Explanation

Solving (I): x²+4x-21=0 gives x = -7, 3. Solving (II): y²+2y-35=0 gives y = -7, 7. When x = -7, y = -7 gives x = y. When x = 3 and y = -7, x > y. When x = 3 and y = 7, x < y. Since the relationship cannot be uniquely determined, the answer is E.
