Question
In the question, two equations I and II are given. You
have to solve both the equations to establish the correct relation between 'p' and 'q' and choose the correct option. I. 5p2 + 2p – 24 = 0 II. q2 + 3q – 54 = 0Solution
ATQ, 5p2 + 2p – 24 = 0 5p2 – 10p + 12p – 24 = 0 5p(p – 2) + 12(p – 2) = 0 (5p + 12)(p – 2) = 0 p = -12/5, 2 p = -2.4, 2 From II: q2 + 3q – 54 = 0 q2 – 6q + 9q – 54 = 0 q(q – 6) + 9(q – 6) = 0 (q + 9)(q – 6) = 0 q = -9, 6 So, no relation can be established between p and q.
