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 and choose the...
I. 6x2 – 7x - 20 = 0
II. 3y2 - y - 14 = 0
I. 3x2 - 16x - 12 = 0
II. 2y2 + 11y + 9 = 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
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
