Solution for 5/x+1-1/x-1=3x/x^2-1 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)

5/x-(1/x)-1+1 = (3*x)/(x^2)-1 // - (3*x)/(x^2)-1

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

5/x-x^-1-3*x^-1-1+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

x = -1
