2*x+6/x-9 = 0
2*x^1+6*x^-1-9*x^0 = 0
(2*x^2-9*x^1+6*x^0)/(x^1) = 0 // * x^2
x^1*(2*x^2-9*x^1+6*x^0) = 0
x^1
2*x^2-9*x+6 = 0
2*x^2-9*x+6 = 0
DELTA = (-9)^2-(2*4*6)
DELTA = 33
DELTA > 0
x = (33^(1/2)+9)/(2*2) or x = (9-33^(1/2))/(2*2)
x = (33^(1/2)+9)/4 or x = (9-33^(1/2))/4
x in { (9-33^(1/2))/4, (33^(1/2)+9)/4}
x in { (9-33^(1/2))/4, (33^(1/2)+9)/4 }
