Question
I). p2 + 22p + 72 = 0, II).
q2 - 24q + 128 = 0 The following question contains two equations as I and II. You have to solve both equations and determine the relationship between them and give the answer.Solution
ATQ, p2 + 22p + 72 = 0 or p2 + 18p + 4p + 72 = 0 or (p + 18) × (p + 4) = 0, p = - 18, - 4 q2 - 24q + 128 = 0 or q2 - 16q - 8q + 128 = 0 or (q - 16) × (q - 8) = 0, q = 16, 8 so, p < q
