Directions (11-15): In the following questions two equations numbered I and II are given. You have to solve both the equations and give answer 

Q11. I. x² = 144 
II. y² - 24y + 144 = 0

If x < y

If x ≤ y

If y < x

If y ≤ x

If x =y or if no relationship can be established.

Solution:

I. x² = 144
⇒x= ±12
II. y² - 24y + 144 = 0
⇒ (y – 12)² = 0
⇒ y – 12 = 0
⇒ y = 12
So, x≤y

Q12. I. 2x² - 9x + 10 = 0 
 II. 2y² - 13y + 20 = 0

If x < y

If x ≤ y

If y < x

If y ≤ x

If x =y or if no relationship can be established.

Solution:

I. 2x² - 9x + 10 = 0
⇒ (x – 2) (2x - 5) = 0
⇒ x=2 or 5/2
II. 2y² - 13y + 20 = 0
⇒ (y - 4) (2y - 5) = 0
⇒ y=4 or 5/2
∴ y ≥ x

Q13. I. 2x² + 15x + 27 = 0
 II. 2y² + 7y + 6 = 0

If x < y

If x ≤ y

If y < x

If y ≤ x

If x =y or if no relationship can be established.

Solution:

I. 2x² + 15x + 27 = 0
⇒ (2x + 9) (x + 3) = 0
⇒ x=-9/2 or-3
II. 2y² + 7y + 6 = 0
⇒ (2y + 3) (y + 2) = 0
⇒ y= -3/2 or-2
∴ x < y

Q14. I. 3x² - 13x + 12 = 0 
 II. 3y² - 13y + 14 = 0

If x < y

If x ≤ y

If y < x

If y ≤ x

If x =y or if no relationship can be established.

Solution:

I. 3x² - 13x + 12 = 0
⇒ (3x – 4) (x - 3) = 0
⇒ x=4/3 or 3
II. 3y² - 13y + 14 = 0
⇒ (3y - 7) (y - 2) = 0
⇒y=7/3 or 2
So, no relation exists between x and y

Q15. I. 5x² + 8x + 3 = 0 
 II. 3y² + 7y + 4 = 0

If x < y

If x ≤ y

If y < x

If y ≤ x

If x =y or if no relationship can be established.

Solution:

I. 5x² + 8x + 3 = 0
⇒ (5x + 3) (x + 1) = 0
⇒ x= -3/5 or-1
II. 3y² + 7y+ 4= 0
⇒ (y + 1) (3y + 4) = 0
⇒y= -1 or -4/3
So, x≥y
