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

Equation 1: x² - 26x + 168 = 0

Equation 2: y² - 23y + 132 = 0

I. 2x² - 15x + 25 = 0

II. 3y² - 10y + 8 = 0

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

Equation 1: x² - 21x + 110 = 0

Equation 2: y² - 23y + 132 = 0

If a and b are the roots of x² + x – 2 = 0, then the quadratic equation in x whose roots are 1/a + 1/b and ab is

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

Equation 1: x² - 24x + 135 = 0

Equation 2: y² - 26y + 153 = 0

I. p² - 19p + 88 = 0   

II. q² - 48q + 576 = 0
