Solution for 2/3t+1/t=5/9 equation: 


D( t )

t = 0

t = 0

t = 0

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

(2/3)*t+1/t = 5/9 // - 5/9

(2/3)*t+1/t-(5/9) = 0

(2/3)*t+1/t-5/9 = 0

2/3*t^1+1*t^-1-5/9*t^0 = 0

(2/3*t^2-5/9*t^1+1*t^0)/(t^1) = 0 // * t^2

t^1*(2/3*t^2-5/9*t^1+1*t^0) = 0

t^1

(2/3)*t^2+(-5/9)*t+1 = 0

(2/3)*t^2+(-5/9)*t+1 = 0

DELTA = (-5/9)^2-(1*4*(2/3))

DELTA = -191/81

DELTA < 0
