Question
I). p2 + 16p + 55 = 0 II).
q2 + 9q + 20 = 0 The question consists of two equations labeled as I and II. Solve both equations, compare their solutions, and establish the relationship between them.Solution
ATQ, p2 + 16p + 55 = 0 p2 + 11p + 5p + 55 = 0 p(p + 11) + 5(p + 11) = 0 p = - 11, - 5 q2 + 9q + 20 = 0 q2 + 5q + 4q + 20 = 0 q(q + 5) + 4(q + 5) = 0 q = - 5, - 4 Hence, p ≤ q
