Which of the following is not a virus

I. 2 x² - 15 + 18 = 0

II. x²- 3 + 2 = 0

I. 10p² + 21p + 8 = 0

II. 5q² + 19q + 18 = 0

The following question contains two equations as I and II.You have to solve both equations and determine the relationship between them.

I. 2y² - 3y – 14 = 0

II. 3x² - 7x + 4 = 0

I. 3p²  + 13p + 14 = 0

II. 8q²  + 26q + 21 = 0

I. 4x² + 9x - 9 = 0

II. 4y² - 19y + 12 = 0

i) p²+p=56                                         

II) q²-17q+72=0

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

Equation 1: x² - 29x + 210 = 0

Equation 2: y² - 27y + 182 = 0

I. 4x² + 3√7 x-7 =0

II. 7y² + 4√7 y-5=0

I. 4x² - 21x + 20 = 0

II. 8y² - 22y + 15 = 0
