Direction: In the following questions two equations numbered I and II are given. You have to solve both the equations and give answer
( 1 ) if x > y
( 2 ) if x ≥ y
( 3 ) if x < y
( 4 ) if x ≤ y
( 5 ) if x = y or the relationship cannot be established.

  1. Ⅰ. 2x2 + 11x + 14 = 0
    Ⅱ. 4y2 + 12y + 9 = 0
    1. 1
    2. 2
    3. 3
    4. 4
    5. 5
Correct Option: C

From the given equations , we have
Ⅰ. 2x2 + 11x + 14 = 0
⇒ 2x2 + 7x + 4x + 14 = 0
⇒ x( 2x + 7 ) + 2( 2x + 7 ) = 0
⇒ ( x + 2 )( 2x + 7 ) = 0

⇒ x =
-7
or -2
2

Ⅱ. 4y2 + 12y + 9 = 0
⇒ ( 2y + 3 )2 = 0
⇒ ( 2y + 3 )( 2y + 3 ) = 0
⇒ y =
-3
,
-3
2
2
From above both equations it is clear that x < y is correct answer .
