Direction: In each of these questions, two equations are given. You have to solve these equations and find out the values of x and y and give answer
( 1 ) x < y
( 2 ) x > y
( 3 ) x ≤ y
( 4 ) x ≥ y
( 5 ) x = y

Ⅰ. 18x2 + 18x + 4 = 0
Ⅱ. 12y2 + 29y + 14 =0

Correct Option: D
From the given above question , we have
From equation Ⅰ. 18x2 + 18x + 4 = 0
⇒ 9x2 + 9x + 2 = 0
⇒ (3x + 2)(3x + 1) = 0
∴ x = - | or, - | ||
⇒ (3y + 2)(4y + 7) = 0
∴ y = - | or, - | ||
