QUESTION: 13

**In the following questions two equations numbered I and II are given. You have to solve both the equations and give answer.**

I. x^{2} + 28 = 11 x

II. 2y^{2} + 18 = 12y

Solution:

I. x^{2} - 11x + 28 = 0

⇒ x^{2} - 7x - 4x + 28 = 0

⇒ x(x - 7) - 4(x - 7) = 0

⇒ x = 7, 4

Also,

II. 2y^{2} + 12y + 18 = 0

⇒ 2y^{2} + 6y + 6y + 18 = 0

⇒ 2y(y + 3) + 6(y + 3) = 0

⇒ y = -3, -3

Hence, x > y

QUESTION: 14

**In the following questions two equations numbered I and II are given. You have to solve both the equations and give answer.**

I. x^{2} + 5x = 7x + 8

II. y^{2} + 7y = 12y + 6

Solution:

I. x^{2} - 2x - 8 = 0

⇒ x^{2} - 4x + 2x - 8 = 0

⇒ x(x - 4) + 2(x - 4) = 0

⇒ x = 4, -2

Also,

II. y^{2} - 5y - 6 = 0

⇒ y^{2} - 6y + y - 6 = 0

⇒ y(y - 6) + 1(y - 6) = 0

⇒ x = 6, - 1

Hence, x < y
