Solution for (1/3-t)+(9/3+t)+(81/t^2)=0 equation: 


D( t )

t^2 = 0

t^2 = 0

t^2 = 0

1*t^2 = 0 // : 1

t^2 = 0

t = 0

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

t-t+81/(t^2)+1/3+9/3 = 0

81*t^-2 = -10/3 // : 81

t^-2 = -10/243

-2 < 0

1/(t^2) = -10/243 // * t^2

1 = -10/243*t^2 // : -10/243

-243/10 = t^2

t belongs to the empty set
