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

Equation 1: 2x² - 8x + 6 = 0

Equation 2: y² - 7y + 10 = 0

I.  2^(x+2)+ 2^(-x)=5

II.  (1/(y+1)+ 1/(y+5))=(1/(y+2)+  1/(y+4))

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

I. 6x² - 47x + 77 =0

II. 6y² - 35y + 49 = 0

Quantity I: The price of rice is decreased by 30%, by how much % the consumption is increase so that the expenditure will decreased by 10%?

I. 2x² - 7x + 3 = 0

II. 8y² - 14y + 5 = 0

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