IBPS SO Prelims Exam Model Paper 2

I equation → 17x2 + 44x – 21 = 0
17x2 + 51x – 7x – 21 = 0
17x (x + 3) – 7 (x + 3) = 0
(17x - 7) (x + 3) = 0
⇒ x = -3 or x =

II equation → 13y2 – 32y + 12 = 0
13y2 - 26y -6y + 12 = 0
13y (y – 2) -6 (y – 2) = 0
(13y - 6) (y - 2) = 0
⇒ y =

or y = 2
Clearly, in both the cases x is less than y.
∴ x < y
