Direction (6-11). In each questions, two equations numbered I and II have been given. You have to solve both the equations and mark the appropriate option.

6)

  1. 2x2 + 9x+9 = 0
  2. 15y2 +16y+4 = 0

Answer:

I. 2x2 + 9x+9 = 0

x = -6/2, -3/2 = -3, -1.5

II. 15y2 +16y+4 = 0

y = -6/15, -10/15 = -0.4,  -0.66

x < y.

7)

  1. 2x3 = √256
  2. 2y2 + 9y +10 = 0

Answer:

I. 2x3 = 16

x= 8

x = 2

II. y = 4/2, 5/2 = 2, 2.5

X ≥ Y.

8)

  1. 6x2 – 11x + 4 = 0
  2. 3y2 – 5y +2 = 0

Answer:

I. 6x2 – 11x + 4 = 0

6 x2 – 8x – 3x + 4 = 0

2x(3x-4)- (3x – 4) = 0

x = 0.5, 1.33

II. 3y2 – 5y +2 = 0

3y2 – 3y – 2y + 2 = 0

y = 1, 0.666

The relationship cannot be determined between X and Y.

9)

  1. 3x2 + 11x+10 = 0
  2. 2y2 + 11y +14 = 0

Answer:

I. 3x2 + 11x+10 = 0

x = -5/3, -6/3 = -1.66, -2

II. 2y2 + 11y +14 = 0

y = -8/2, -3/2 = -4, -1.5

The relationship cannot be determined between X and Y.

10)

  1. 12x2 + 11x+2 = 0
  2. 12y2 + 7y +1 = 0

Answer:

I. 12x2 + 11x+2 = 0

x = -8/12, -3/12 = -0.66, -0.25

II. 12y2 + 7y +1 = 0

y = -3/12, -4/12 = -0.25, -0.33

The relationship cannot be determined between X and Y.

11)

  1. 21x2 + 10x+1 = 0
  2. 24y2 + 26y +5 = 0

Answer:

I. 21x2 + 10x+1 = 0

x = -7/21, -3/21 = -0.33, -0.1428

II. 24y2 + 26y +5 = 0

y = -0.83, -0.25

The relationship cannot be determined between X and Y.
