What would be the case when y=2 and x=-11? (Question:99805.2)

Your answer satisfies the given option?

Question:
DIRECTIONS: In each of the following questions, two equations are given. You have to solve these equations and give answer if:

I. 6x2 +77x +121 = 0

II. y2 + 9y – 22 =0
Options:
A)

x < y

B)

x > y

C)

x ≥ y

D)

x ≤ y

E)

x = y or the relation can’t be determined   

Solution:

Ans (e)  

I. 6x2 +77x +121 = 0

⇒6x2 + 66x + 11x + 121 = 0

⇒6x (x  + 11) + 11 (x + 11) = 0

⇒ (x + 11) (6x + 11) = 0

⇒ x = - 11 or – 11/6 

II. y2 + 11y – 2y – 22 = 0

⇒ y (y + 11) -2 (y + 11) = 0

⇒ (y – 2) (y + 11) = 0

⇒ y = 2 or -11
