Compound gives buttery flavor

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

I. 3q² -29q +18 = 0

II. 9p² - 4 = 0

I. 2x² - 15x + 25 = 0

II. 3y² - 10y + 8 = 0

I. x³=  ((4)⁵+ (15)³)/(3)⁴

II. 8y³=(-13)³÷ √1521+ (3y)³ 

I. 2x² – 10x – 48 = 0

II. y² – 16y – 297 = 0

I. 27x⁶ - 152x³ + 125 = 0

II. 216y⁶ - 91y³ + 8 = 0

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

I. 8x² + 2x – 3 = 0

II. 6y² + 11y + 4 = 0

If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?

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

Equation 1: 2x² - 8x + 6 = 0

Equation 2: y² - 7y + 10 = 0
