What is the bond angle between CF₄, CCl₄,

I. x² – 12x + 32 = 0

II. y² + y - 20 = 0

I. 8x – 3y = 85

II. 4x – 5y = 67

I. 2y² - 35y + 132 = 0

II. 2x² - 31x + 110 = 0

I. 99 x² + 31 x – 110 = 0

II. 6y² - 31y + 35 = 0

I). p² - 26p + 165 = 0

II). q² + 8q - 153 = 0

I. 17x² - 26x – 16 = 0

II. 17y²- 26y + 9 = 0

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

I. 2y² – 19y + 35 = 0

II. 4x² – 16x + 15 = 0

I. 2x² - 15x  + 13 = 0

II. 3y² - 6y + 3 = 0
