Directions (49-53) : In the given 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 relationship between x and y cannot be established
I. \( \large 2x^{2} \) +11x + 14 = 0 II. \( \large 2y^{2} \) +15y + 28 = 0
Correct Answer: Description for Correct answer:
I.
\( \large 2x^{2} \) + 11x + 14 = 0
\( \large 2x^{2} \) + 7x + 4x = 0
x(2x + 7) + 2(2x + 7) = 0
(x + 2)(2x + 7) = 0
=> x = -2, -\( \Large \frac{7}{2} \)
II.
\( \large 2y^{2} \) + 15y + 28 = 0
\( \large 2y^{2} \) + 7y + 8y +28 =0
y(2y + 7) + 4(2y + 7) = 0
=> y = -4, -\( \Large \frac{7}{2} \)
S0, x \( \large \ge \) y
