Solution for 1-3/x^2=2/x equation: 


D( x )

x = 0

x^2 = 0

x = 0

x = 0

x^2 = 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

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

1-(3/(x^2)) = 2/x // - 2/x

1-(2/x)-(3/(x^2)) = 0

1-2*x^-1-3*x^-2 = 0

t_1 = x^-1

1-3*t_1^2-2*t_1^1 = 0

1-3*t_1^2-2*t_1 = 0

DELTA = (-2)^2-(-3*1*4)

DELTA = 16

DELTA > 0

t_1 = (16^(1/2)+2)/(-3*2) or t_1 = (2-16^(1/2))/(-3*2)

t_1 = -1 or t_1 = 1/3

t_1 = -1

x^-1+1 = 0

1*x^-1 = -1 // : 1

x^-1 = -1

-1 < 0

1/(x^1) = -1 // * x^1

1 = -1*x^1 // : -1

-1 = x^1

x = -1

t_1 = 1/3

x^-1-1/3 = 0

1*x^-1 = 1/3 // : 1

x^-1 = 1/3

-1 < 0

1/(x^1) = 1/3 // * x^1

1 = 1/3*x^1 // : 1/3

3 = x^1

x = 3

x in { -1, 3 }
