Quantitative Aptitude (SBI-PO) Quadratic Equations

Direction: In the following question two equations are given in variables x and y. You have to solve these equations and determine the relation between x and y.

I. x²= 256

II. y² + 18y + 17 = 0

y > x

x > y

x ≤ y

x ≥ y

x = y or no relation can be established

Explanation:

x²= 256
⇒ x = 16, −16
y² + 18y + 17 = 0
⇒ y² + 17y + y + 17 = 0
⇒ y(y + 17) + 1(y + 17) = 0
⇒ (y + 17)(y + 1) = 0
⇒ y = −17, −1
Thus, no relation can be established.
