Q:

In each of the following questions two equations I and II are given. Solve both the equations and give answer:
$I . x^{2} + 2 x - 195 = 0 II . y^{2} + 30 y + 225 = 0$

A) x = y or relation can’t be established between x and y	B) x > y
C) x < y	D) x ≥ y

Answer & Explanation Answer: D) x ≥ y

Explanation:

I. x2 + 2x - 195 = 0 = (x+15) (x-13) => x = -15, 13

II. y2 + 30y + 225 = 0 = (y+15) (y+15) => y = -15, -15

So x ≥ y
