Which one of the following is responsible for pulses to

I. x² + 24x + 143 = 0

II. y² + 12y + 35 = 0

I: 2x² - 8x + 6 = 0

II: 3y² - 12y + 9 = 0

I. 2x² + 5x + 2 = 0

II. 4y² = 1

In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.

I. x

I. 7p + 8q = 80

II. 9p – 5q = 57

I. 2y² - 15y + 18 = 0

II. 2x² + 9x - 18 = 0

I. (4x-5)³ +  1/(4x-5)³  = 2

II. 2[(y+1/y)²- 2]- 9(y+1/y)= -14

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

I. 9x² + 45x + 26 = 0

II. 7y² – 59y − 36 = 0

I. 35x² - 24x – 35 = 0

II. 72y² - 145y + 72 = 0
