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) (x^2 - 1.2x - 1.6 = 0) b) (y^2 + 2.3y + 1.2 = 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

C Correct answer
Explanation

Solving x² - 1.2x - 1.6 = 0 gives x = 2, -0.8. Solving y² + 2.3y + 1.2 = 0 gives y = -0.8, -1.5. Since x = 2 > y = -1.5 but x = -0.8 = y = -0.8, the relationship is x ≥ y.
