Solution for 6/x-2x=9 equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

6/x-(2*x) = 9 // - 9

6/x-(2*x)-9 = 0

6/x-2*x-9 = 0

6*x^-1-2*x^1-9*x^0 = 0

(6*x^0-2*x^2-9*x^1)/(x^1) = 0 // * x^2

x^1*(6*x^0-2*x^2-9*x^1) = 0

x^1

6-2*x^2-9*x = 0

6-2*x^2-9*x = 0

DELTA = (-9)^2-(-2*4*6)

DELTA = 129

DELTA > 0

x = (129^(1/2)+9)/(-2*2) or x = (9-129^(1/2))/(-2*2)

x = (129^(1/2)+9)/(-4) or x = (9-129^(1/2))/(-4)

x in { (129^(1/2)+9)/(-4), (9-129^(1/2))/(-4)} 

x in { (129^(1/2)+9)/(-4), (9-129^(1/2))/(-4) }
