Multiple choice

In the following question two equations numbered I and II are given. You have to solve both the equations and choose the correct option. I. (x^2 + 15x – 76 = 0) II. (y^2 – 23y + 76 = 0)

  1. $x > y$
  2. $x < y$
  3. $x ≥ y$
  4. $x ≤ y$
  5. $x = y or relation can’t be established$

D Correct answer
Explanation

Solving x²+15x-76=0 gives x = [-15±√(225+304)]/2 = [-15±23]/2 = 4 or -19. Solving y²-23y+76=0 gives y = [23±√(529-304)]/2 = [23±15]/2 = 19 or 4. For x=-19, x
