Which soil-forming factor is classified as "active"?

I.  3y² + 13y - 16 = 0

II. 3x² – 13x + 14 = 0

I. 2x² + 12x + 18 = 0

II. 3y² + 13y + 12 = 0

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

Equation 1: x² - 32x + 252 = 0

Equation 2: y² - 30y + 221 = 0

I. 2x² - 5x - 33 =0

II. 2y² + 5y - 25 = 0

If 3x – 2y = 10 and xy = 11, the value of 27x³ – 8y³ is __________.

I. 2x² – 5x – 63 = 0

II. 2y² – 7y – 72 = 0

I. 4p² + 17p + 15 = 0

II. 3q² + 19q + 28 = 0

I. x + 1 = ³√ 9261

II. y + 1 = √ 324

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

I. 2x² – 5x – 12 = 0

II. 2y² + 13y + 20 = 0
