Identify the word that is

I. 5x² = 19x – 12

II. 5y² + 11y = 12

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

Equation 1: x² - 5x + 6 = 0

Equation 2: y² - 7y + 12 = 0

I. x² + x – 42 = 0

II. y² + 6y – 27 = 0

I. 6x² + 37x + 45 = 0

II. 3y² - 11y + 6 = 0

I. 8x² - 2x – 15 = 0

II. 12y² - 17y – 40 = 0

I. 2x² - 11x + 12 = 0

II. 12y² + 29y + 15 = 0

LCM of 'x' and 'y' is 30 and their HCF is 1 such that {10 > x > y > 1}.

I. 2p²- (x + y) p + 3y = 0

II. 2q² + (9x + 2) = (3x + y) q

I. 64x² - 64x + 15  = 0     

II. 21y² - 13y + 2  =0

I. 3x² + 3x - 60 = 0         

II. 2y² - 7y + 5 = 0
