For the two given equations I and II.

I. \( \Large p^{2} \)+ 5p + 6 = 0

II.\( \Large q^{2} \) + 3q + 2 = 0

A) p is greater than q
B) p is smaller than q.
C) p is equal to q.
D) p is either equal to or smaller than q.

Correct Answer:




D) p is either equal to or smaller than q.

Description for Correct answer:
I. => \( \Large p^{2} \) + 3p + 2p + 6 = 0

=> p ( p + 3 ) + 2 ( p + 3 ) = 0

=> ( p + 3 ) ( p + 2 ) = 0

=> p = - 2 or - 3

II. => \( \Large q^{2} \) + q + 2q + 2 = 0

=> q ( q + 1 ) + 2 ( q + 1 ) = 0

=> ( q + 1 ) ( q + 2 ) = 0

=> q = - 1 or - 2

Obviously p \( \Large \leq \) q
