Multiple choice

In each of these questions, two equations (a) and (b) are given. You have to solve both the equations and choose the correct option. a) (4x^2 + x - 14 = 0) b) (y^2 - 15y + 56 = 0)

  1. x > y

  2. x ≤ y

  3. x ≥ y

  4. x < y

  5. x = y or relationship between x and y can't be established

D Correct answer
Explanation

Solving 4x² + x - 14 = 0 gives x = 1.75, -2. Solving y² - 15y + 56 = 0 gives y = 7, 8. Both positive roots of x (1.75) are less than both positive roots of y (7, 8), so x < y.
