Direction: In this question 2 equations numbered I and II are given. You have to solve both the equations and find out the correct option.
-
Ⅰ. 24x2 + 38x + 15 = 0
Ⅱ.12y2 + 28y + 15 = 0
-
- x ≤ y
- x > y
- x ≥ y
- x < y
- x = y, or Relationship between x and y cannot be established
Correct Option: C
According to question ,we can say that
From equation Ⅰ. 24x2 + 38x + 15 = 0
⇒ 24x2 + 20x + 18x + 15 = 0
⇒ 4x(6x + 5) + 3(6x + 5) = 0
⇒ (4x + 3)(6x + 5) = 0
∴ x = - | , - | ||
⇒ 12y2 + 18y + 10y + 15 = 0
⇒ 6y(2y + 3) + 5(2y + 3) = 0
⇒ (6y + 5)(2y + 3) = 0
∴ y = - | , - | ||
