Algebra Level 3

Simplify $\dfrac{x+1}{x^3-x}$ as much as you can.

-------------------------------------------------------------------------------------------------------------------------

Note: $x^3 \neq 1$

\dfrac{1}{x^3}-\dfrac{1}{x}

\dfrac{1}{x^2-1}

\dfrac{1}{x^2+x}

\dfrac{1}{x^3}

\dfrac{1}{x^2-x}

\dfrac{1}{x^2}-\dfrac{1}{x^3}
