I. 14p² – 135p + 81 = 0

II. 7q² – 65q + 18 = 0

I. x³ = 1728

II. y² – 15y + 56 = 0

I. 7x² + 27x + 18 = 0

II. 19y² - 27y + 8 = 0

Equation 1: x² - 250x + 15625 = 0

Equation 2: y² - 240y + 14400 = 0

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. 3p²  + 13p + 14 = 0

II. 8q²  + 26q + 21 = 0

I. x ² + 5 x  + 6 = 0                 

II. y²+ 7 y  + 12= 0

Roots of the quadratic equation 2x² + x – 528 = 0 is

l. x² - 16x + 64 = 0

II. y² = 64

If x + 1/x = 3, find x² + 1/x².
