In case of full Crowding out effect what is the shape of

I. 8a² – 22a+ 15 = 0

II. 12b² - 47b + 40=0

I. 6 y² + 11 y – 7= 0

II. 21 x² + 5 x – 6 = 0

I. 84x² - 167x - 55 = 0

II. 247y² + 210y + 27 = 0

I. 2x² + 11x + 12 = 0

II. 2y² + 19y + 45 = 0

I. 2x² – 5x - 12 = 0

II. y² – 11y + 30 = 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%?

Equation 1: x² - 144x + 5184 = 0

Equation 2: y² - 130y + 4225 = 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.

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

Equation 1:  3x² + 6√7x - 315 = 0
