Quadratic Equations

Question
3 out of 10
 

In each of these questions, two equations are given. You have to solve these equations and find out the values of x and y and :


I. 17x2 + 48x = 9 II. 13y2 = 32y −12



A if x <y

B if x >y

C if x ≤ y

D if x ≥ y

E if x = y

Ans. A 17x2 + 48x – 9 = 0

17x2 + 51x – 3x – 9 = 0

(17x – 3) (x+3) = 0, x = 3/17, -3

13y2 – 32y + 12 = 0

Y = x < y
