D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
1/x-1+3 = (2*x)/3-x // - (2*x)/3-x
x-((2*x)/3)+1/x-1+3 = 0
(-2/3)*x+x+1/x-1+3 = 0
1/3*x^1+1*x^-1+2*x^0 = 0
(1/3*x^2+2*x^1+1*x^0)/(x^1) = 0 // * x^2
x^1*(1/3*x^2+2*x^1+1*x^0) = 0
x^1
(1/3)*x^2+2*x+1 = 0
(1/3)*x^2+2*x+1 = 0
DELTA = 2^2-(1*4*(1/3))
DELTA = 8/3
DELTA > 0
x = ((8/3)^(1/2)-2)/(2*(1/3)) or x = (-(8/3)^(1/2)-2)/(2*(1/3))
x = 3/2*((8/3)^(1/2)-2) or x = -3/2*((8/3)^(1/2)+2)
x in { -3/2*((8/3)^(1/2)+2), 3/2*((8/3)^(1/2)-2)}
x in { -3/2*((8/3)^(1/2)+2), 3/2*((8/3)^(1/2)-2) }
