IBPS SO Prelims Exam Model Paper 7

Given:
I. 2x2 - 9x + 10 = 0
II. 2y2 - y - 15 = 0
Calculation:
From I
2x2 - 9x + 10 = 0
⇒ 2x2 - 5x - 4x + 10 = 0
⇒ x(2x - 5) - 2(2x - 5) = 0
⇒ (2x - 5)(x - 2) = 0
⇒ x = (

), 2
From II
2y2 - y - 15 = 0
⇒ 2y2 - 6y + 5y - 15 = 0
⇒ 2y(y - 3) + 5(y - 3) = 0
⇒ (y - 3)(2y + 5) = 0
⇒ y = 3, -(
