For the hydrogenation oil, the catalyst required is

I. 2b² + 31b + 99 = 0

II. 4a² + 8a - 45 = 0

I. y² - 7 y – 18 = 0

II. x² + 10 x + 16 = 0

I. 2x² - 11x + 12 = 0

II. 12y² + 29y + 15 = 0

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

I. 2p² - 11p + 12 = 0

II. 2q² - 17q + 36 = 0

I. 3x² - 14x + 15 = 0

II. 15y²- 34 y + 15 = 0

I. 35 y² + 58 y + 24 = 0

II. 21 x² + 37 x + 12 = 0

I. 27x² + 120x + 77 = 0

II. 56y² + 117y + 36 = 0

 If 4x = 40, 3y = 33, what is the value of 6x + 4y?

I. 2x² + 12x + 18 = 0

II. 3y² + 13y + 12 = 0
