Directions (1-5): Solve the following equations and mark the correct option given below.

1. I. x² – 20x + 91 = 0
II. y² – 32y + 247 = 0
(a) if x<y
(b) if x>y
(c) if x≤y
(d) if x≥y
(e) if x=y or no relation can be established

Answer & Explanation
 Ans. c
Exp. I. x² – 20x + 91 = 0
x² – 13x – 7x + 91 = 0
x (x – 13) – 7(x- 13) =0
(x -7) (x- 13) = 0
x=7,13
II. y² – 32y + 247 = 0
y² – 19y – 13y +247 = 0
y (y – 19) – 13(y-19) = 0
(y – 13) (y- 19) = 0
y= 13,19
x≤y

2. I. x² + 19x + 84 = 0
II. y² – 25y + 156 = 0
(a) if x<y
(b) if x>y
(c) if x≤y
(d) if x≥y
(e) if x=y or no relation can be established

Answer & Explanation
 Ans. a
Exp. I. x² + 19x + 84 = 0
x² + 12x + 7x + 84 = 0
x (x +12) + 7(x+12) =0
(x +7) (x+ 12) = 0
x=-7,-12
II. y² – 25y + 156 = 0
y² – 12y – 13y +156 = 0
y (y – 12) – 13(y-12) = 0
(y – 13) (y- 12) = 0
y= 13,12
x<y

 

3. I. x² – 4 = 0
II. y² + 6y + 9 = 0
(a) if x<y
(b) if x>y
(c) if x≤y
(d) if x≥y
(e) if x=y or no relation can be established

Answer & Explanation
 Ans. b
Exp. I. x² – 4 = 0
x² =4
x = 2, –2
II. y² +6y + 9 = 0
y2 + 3y + 3y + 9 =0
y (y + 3) + 3(y+ 3) = 0
(y +3) (y+ 3) = 0
y = –3, –3
x>y

 

4. I. x² – 7x + 12 = 0
II. y² + y – 12 = 0
(a) if x<y
(b) if x>y
(c) if x≤y
(d) if x≥y
(e) if x=y or no relation can be established

Answer & Explanation
 Ans. d
Exp. I. x² – 7x + 12 = 0
x² – 4x – 3x + 12 = 0
x (x – 4) – 3(x- 4) =0
(x -3) (x- 4) = 0
x=3,4
II. y² + y – 12 = 0
y² + 4y – 3y -12 = 0
y (y + 4) – 3(y + 4) = 0
(y – 3) (y + 4) = 0
y= 3,-4
x≥y

 

5. I. 2x²+ 11x + 14 = 0
II. 4y² + 12y + 9 = 0
(a) if x<y
(b) if x>y
(c) if x≤y
(d) if x≥y
(e) if x=y or no relation can be established

Answer & Explanation
 Ans. a
Exp. I. 2x² + 11x + 14 = 0
2x² + 4x + 7x + 14 = 0
2x (x +2) + 7(x+2) =0
(2x +7) (x+ 2) = 0
x=-7/2,-2
II. 4y² + 12y +9 = 0
4y² + 6y + 6y +9 = 0
2y (2y + 3) + 3(2y + 3) = 0
(2y + 3) (2y + 3) = 0
y= -3/2,-3/2
x<y
