Multiple choice

In each question below two equations are given. On the basis of these you have to find out the relationship between x and y. $I. (x(x+25) + 156 = 0) II. (y^2 - 144 = 0)$

  1. If x = y or relation cannot be established

  2. If x > y

  3. If x < y

  4. If x ≤ y

  5. If x ≥ y

D Correct answer
Explanation

x(x+25) + 156 = 0 gives x² + 25x + 156 = 0, x = -12, -13. y² - 144 = 0 gives y = 12, -12. x values: -12, -13. y values: 12, -12. When y = 12, x < y. When y = -12, x = -12 gives x = y, and x = -13 gives x < y. So x ≤ y always holds.
