According to the Planning Commission of India

(i) 2x² + 14x - 16 = 0

(ii) y² – y – 12 = 0

I. 6x²- 41x+13=0

II. 2y²- 19y+42=0

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

Equation 1: x² - 40x + 300 = 0

Equation 2: y² - 30y + 216 = 0

I. 49y²+ 35y + 6 = 0

II. 12x²+ 17 x + 6 = 0

I. 6y² – 23y + 20 = 0

II. 4x² – 24 x + 35 = 0

I. 2y²+ 13y + 15 = 0

II. 2x²+ 11 x + 12 = 0

I. p² – 2p – 15 = 0

II. q² + 4q – 12 = 0

I. x² – 19x + 88 = 0

II. (y + 4)² = 121

I. 17x² - 26x – 16 = 0

II. 17y²- 26y + 9 = 0

I. 5x² – 18x + 16 = 0

II. 3y² – 35y - 52 = 0
