Question Paper from: SBI PO Prelims 2017
I. 2x² - 7x + 6 = 0
II. y² - 3y + 2 = 0
x = y or no relation can be established
x ≤ y
x ≥ y
x > y
x < y
Solution:
Chapter Name: Quadratic Equation
Difficulty Level: Moderate
2x² - 7x + 6 = 0
⇒ 2x² - 4x - 3x + 6 = 0
⇒ 2x(x -2) - 3(x - 2) = 0
⇒ (x - 2)(2x - 3) = 0
⇒ x = , 2
y² - 3y + 2 = 0
⇒ y² - 2y - y + 2 =0
⇒ y(y - 2) - 1(y - 2) = 0
⇒ (y - 2)(y - 1) = 0
⇒ y = 2, 1
No relation can be established between x & y
