Directions (11-15): Solve the following equations and mark the correct option given below. 


Q11. I. x² – 27x + 180 = 0 
II. y² – 7y = 60

if x>y
if x≥y
if y>x
if y≥x
if x=y or no relation can be established
Solution:

I. x² – 27x + 180 = 0
x² – 12x – 15x + 180 = 0
x (x – 12) –15(x – 12) = 0
(x – 15) (x – 12) = 0
x = 15, 12
II. y² – 7y – 60 = 0
y² – 12y + 5y – 60 = 0
y (y – 12) +5 (y – 12) = 0
(y + 5) (y – 12) = 0
y= -5, 12
⇒ x ≥ y

Q12. I. x² – 59x + 868 = 0 
II. y² – 53y + 702 = 0

if x>y
if x≥y
if y>x
if y≥x
if x=y or no relation can be established
Solution:

I. x² – 59x + 868 = 0
x² – 28x – 31x + 868 = 0
x (x – 28) – 31 (x – 28) = 0
(x – 31) (x – 28) = 0
x = 28, 31
II. y² – 53y + 702 = 0
y² – 27y – 26y + 702 = 0
y (y – 27) – 26(y – 27) = 0
(y– 27) (y – 26) = 0
y = 26, 27
⇒ x > y

Q13. I. 100x² – 120x + 32 = 0 
II. 10y² – 17y + 6 = 0

if x>y
if x≥y
if y>x
if y≥x
if x=y or no relation can be established
Solution:

I. 100x² – 120x + 32 = 0
100x² – 40x – 80x + 32 = 0
20x (5x – 2) – 16(5x – 2) = 0
(20x – 16) (5x – 2) = 0
x = 4/5, 2/5
II. 10y² – 17y + 6 = 0
10y² – 12y – 5y + 6 = 0
2y (5y – 6) – 1 (5y – 6) = 0
(2y – 1) (5y – 6) = 0
y = 1/2, 6/5
⇒ No relation

Q14. I. 15x² – 22x + 8 = 0 
II. 12y² – 5y – 2 = 0

if x>y
if x≥y
if y>x
if y≥x
if x=y or no relation can be established
Solution:

I. 15x² – 22x + 8 = 0
15x² – 12x – 10x + 8 = 0
3x (5x – 4) –2 (5x – 4) = 0
(5x – 4) (3x– 2) = 0
x = 4/5, 2/3
II. 12y² – 5y – 2 = 0
12y² – 8y + 3y – 2 = 0
4y (3y – 2) + 1 (3y – 2) = 0
(4y + 1) (3y – 2) = 0
y = -1/4, 2/3
⇒ x ≥ y

Q15. I. x² + 8x + 15 = 0 
II. y² – 2y – 8 = 0

if x>y
if x≥y
if y>x
if y≥x
if x=y or no relation can be established
Solution:

I. x²+ 8x + 15 = 0
x² + 5x + 3x + 15 = 0
x (x + 5) + 3 (x+ 5) = 0
(x + 5) (x + 3) = 0
x = –5, –3
II. y² – 2y – 8 = 0
y² – 4y + 2y – 8 = 0
y (y – 4) + 2(y – 4) = 0
(y – 4) (y + 2) = 0
y= –2, 4
⇒ x < y
