In which method of planting maximum number of plants

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. x² + (9x/2) + (7/2) = - (3/2)

II. y² + 16y + 63 = 0

I. (4x-5)³ +  1/(4x-5)³  = 2

II. 2[(y+1/y)²- 2]- 9(y+1/y)= -14

I. 4x² - 21 x + 20 = 0

II. 8y² - 22 y + 15 = 0

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

Equation 1: x² - 24x + 143 = 0

Equation 2: y² - 26y + 165 = 0

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

Equation 1: 21x² - 122x + 160 = 0

I. x² - 5x - 14 = 0

II. y² - 16y + 64 = 0

I. 15/(√x)+9/(√x)=11√x

II. (√y)/4 + (5√y)/12 = 1/(√y)

I.8^(x+3) +  8^(-x) =72 

II. 5^{(y + 5)} + 5^(-y) = 150 

I. 7x² + 52x + 21 = 0

II. 6y² + 7y - 24 = 0
