5.In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y and choose the correct option.
I. x2-10x + 24 = 0
II. y2– 5y – 24 = 0
a. x > y
b. x < y
c. x = y or the relationship cannot be established
d. x ≥ y
e. x ≤ y

C. x = y or the relationship cannot be established

Directions: (6-10) In the questions, two equations I and II are given. You have to solve both the equations and give answer.

6. I. x2+ 2x – 143 = 0
II. y2+ y – 156 = 0

a. if x >y
b. if x < y
c. if x = y, or relation cannot be established between x and y
d. if x ≥ y
e. if x ≤ y

C. if x = y, or relation cannot be established between x and y

x2+ 2x – 143 = 0
=> x2+ 13x – 11x – 143 = 0
=> x(x+13) – 11(x+13) = 0
=> (x-11)(x+13) = 0
=> x = 11, -13
y2+ y – 156 = 0
=> y2+ 13y – 12y – 156 = 0
=> y(y+13) – 12(y+13) = 0
=> (y-12)(y+13) = 0
y = 12, -13
Therefore, relation cannot be established between x and y.

7. I. 42x– 71x + 30 = 0
II. 16y2– 32y + 15 = 0

a. if x >y
b. if x < y
c. if x = y, or relation cannot be established between x and y
d. if x ≥ y
e. if x ≤ y

C. if x = y, or relation cannot be established between x and y

42x2– 71x + 30 = 0
=> 42x2– 36x – 35x + 30 = 0
=> 6x(7x-6) – 5(7x-6) = 0
=> (6x-5)(7x-6) = 0
=> x = 5/6, 6/7
16y2– 32y + 15 = 0
=> 16y2– 20y – 12y + 15 = 0
=> 4y(4y-5) – 3(4y-5) = 0
=> (4y-3)(4y-5) = 0

y = 3/4, 5/4
Therefore, relation cannot be established between x and y.

8.  I. 9x2 – 9x – 4 = 0
II. 9y2+ 9y + 2 = 0

a. if x >y
b. if x < y
c. if x = y, or relation cannot be established between x and y
d. if x ≥ y
e. if x ≤ y

D. if x ≥ y

9x2 – 9x – 4 = 0
=> 9x2– 12x + 3x – 4 = 0
=> 3x(3x-4) + 1(3x-4) = 0
=> (3x+1)(3x-4) = 0
=> x = -1/3, 4/3
9y2+ 9y + 2 = 0
=> 9y2+ 3y + 6y + 2 = 0
=> 3y(3y+1) + 2(3y+1) = 0
=> (3y+2)(3y+1) = 0
y = -2/3, -1/3
x ≥ y

9. I. 6x2 – 23x + 22 = 0
II. 6y2 + 5y – 25 = 0

a. if x >y
b. if x < y
c. if x = y, or relation cannot be established between x and y
d. if x ≥ y
e. if x ≤ y

A. if x >y

6x2– 23x + 22 = 0
=> 6x2– 12x – 11x + 22 = 0
=> 6x(x-2) – 11(x-2) = 0
=> (6x-11)(x-2) = 0
=> x = 11/6, 2
6y2+ 5y – 25 = 0
=> 6y2– 10y + 15y – 25 = 0
=> 2y(3y-5) + 5(3y-5) = 0
=> (2y+5)(3y-5) = 0
y = -5/2, 5/3

10. I. 8x2+ 6x + 1 = 0
II. 20y2+ y – 1 = 0

a. if x >y
b. if x < y
c. if x = y, or relation cannot be established between x and y
d. if x ≥ y
e. if x ≤ y

E. if x ≤ y

8x2+ 6x + 1 = 0
=> 8x2+ 2x + 4x + 1 = 0
=> 2x(4x+1) + 1(4x+1) = 0
=> (2x+1)(4x+1) = 0
=> x = -1/2, -1/4
20y2+ y – 1 = 0
=> 20y2– 4y + 5y – 1 = 0
=> 4y(5y-1) + 1(5y-1) = 0
=> (4y+1)(5y-1) = 0
y = -1/4, 1/5
x ≤ y
