Multiple choice

In each of the following question, equations are given. You have to solve them and state the correct relationship- I. (P^2 + 2P + 1 = 0) II. (Q^2 = 4)

  1. If P ≥ Q

  2. If P > Q

  3. If P < Q

  4. If P ≤ Q

  5. If P = Q or relationship can not be established

E Correct answer
Explanation

From equation I: P² + 2P + 1 = 0 means (P + 1)² = 0, so P = -1. From equation II: Q² = 4, so Q = ±2. When Q = 2, P < Q. When Q = -2, P > Q. Since we cannot establish a consistent relationship (P could be less than or greater than Q depending on which value of Q we choose), option E is correct.
