Question Paper from: SBI PO Prelims 2017
I. 2x² + 5x + 2 = 0
II. y² + 9y + 20 = 0
1:
x = y or no relation can be established
2:
x ≤ y
3:
x ≥ y
4:
x > y
5:
x < y
Solution:
Chapter Name: Quadratic Equation
Difficulty Level: Moderate
2x² + 5x + 2 = 0
⇒ 2x² + 4x + x + 2 = 0
⇒ 2x(x + 2) + 1(x + 2) = 0
⇒ (x + 2)(2x + 1) = 0
⇒ x = -2,
y² + 9y + 20 = 0
⇒ y² + 4y + 5y + 20 = 0
⇒ y(y + 4) + 5(y + 4) = 0
⇒ (y + 4)(y + 5)
⇒ y = -4, -5
x > y
