Choose the odd one from the

I. 3x² = 2x² + 9x – 20

II. 3y² = 75

Solve the quadratic equations and determine the relation between x and y:

Equation 1: 19x² - 92x + 73 = 0

Equation 2: 17y² - 76y + 59 = 0

In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer   

I. x² – 7x + 12 = 0

II. y² – 7y + 10 = 0

I. 63x² + 146x + 80 = 0

II. 42y² + 109y + 70 = 0

I. 3x² – 17x + 10 = 0

II. y² – 17y + 52 = 0

I. x² + (9x/2) + (7/2) = - (3/2)

II. y² + 16y + 63 = 0

I. 40 x² - 93 x + 54 = 0

II. 30 y² - 61 y + 30 = 0

I. 2x² - 7x + 3 = 0

II. 8y² - 14y + 5 = 0

I. 10p² + 21p + 8 = 0

II. 5q² + 19q + 18 = 0
