If the edge of the cube is increased by 100%, then find the

I. 2x² – 5x – 63 = 0

II. 2y² – 7y – 72 = 0

If x² - 3x - 18 = 0 and y² + 9y + 18 = 0, which of the following is true?

Solve the given two equations and answer the two questions that follow as per the instructions given below.

I. 2x² + 3x - 9 = 0

II. 3y² - y - 10 = 0

I. x² + x – 42 = 0

II. y² + 6y – 27 = 0

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

Equation 1: x² - 20x + 96 = 0

Equation 2: y² - 18y + 72 = 0

I. x² – 12x + 32 = 0

II. y² + y - 20 = 0

l. x² - 16x + 64 = 0

II. y² = 64

I. x² - 5x - 14 = 0

II. y² - 16y + 64 = 0

I. 10x² - 11x + 3 = 0

II. 42y² - 23y – 10 = 0
