Question
I). p2 - 26p + 165 = 0 II).
q2 + 8q - 153 = 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, I). p2 - 26p +165 = 0 p² - 15p – 11p + 165 = 0 (p - 15)(p - 11) = 0 p = 15, 11 II). q2  + 8q – 153 = 0 q² - 9q + 17q – 153 = 0 (q+17) (q – 9) = 0 q = -17, 9 Therefore p > q.
