In following question, two equations are given, you have to solve them and chose the correct option: x2 + 11x + 30 = 0, y2 + 7y + 12 = 0

In following question, two equations are given, you have to solve them and chose the correct option:

x² + 11x + 30 = 0,

y² + 7y + 12 = 0

A x = y or relation cannot be determined

B x > y

C x < y

D x ≥ y

E x ≤ y

Correct Answer: Option C

x² + 11x + 30 = 0

⇒ x² + 6x + 5x + 30 = 0

⇒ x(x+6) + 5(x+6) = 0

⇒ (x+5) (x+6)=0

X = -5, -6

y² +7y + 12 = 0

⇒ y² + 4y + 3y + 12 = 0

⇒ y (y+4) + 3(y+4) = 0

⇒ (y+3) (y+4) = 0

Y =-3, -4

∴ x < y
