Which one of the following is NOT a part of the/ seven

Equation 1: x² - 45x + 500 = 0

Equation 2: y² - 60y + 600 = 0

I. x² - 208 = 233

II. y² + 47 - 371 = 0

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

Equation 1: 4x² - 12x + 9 = 0

Equation 2: 2y² + 10y + 12 = 0

i) p²+p=56                                         

II) q²-17q+72=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 + 24x + 143 = 0

II. y² + 12y + 35 = 0

I. 195x² - 46x - 21 = 0

II. 209y² + 13y - 12 = 0

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

Equation 1: x² - 24x + 143 = 0

Equation 2: y² - 26y + 165 = 0

I. 5x² = 19x – 12

II. 5y² + 11y = 12

I. 5x² – 18x + 16 = 0

II. 3y² – 35y - 52 = 0
