Quantitative Aptitude (SBI-CL) Quadratic Equations

Directions: In each of these questions, two equations (I) and (II) are given.

I. 2x² + 19x + 42 = 0

II. 4y² + 43y + 30 = 0

x > y

. x < y

x ≥ y

x ≤ y

x = y or no relation can be established between ‘x’ and ‘y’.

I. 2x² + 19x + 42 = 0

2x² + 12x + 7x + 42 = 0 2x (x+6) + 7(x +6) = 0

(2x+7) (x+6) = 0 x = -7/2, -6

II. 4y² + 43y + 30 = 0

4y2 +40y + 3y + 30 = 0

4y(y + 10) + 3(y + 10) (4y + 3)(y + 10) = 0

y = -3/4, -10

So answer is no relation.
