The inverse? Totally easy, it’s 1 / (x^3 + x) [drops mic]

[The inverse isn’t that bad but it’s still not fun to do on paper](https://latex.codecogs.com/png.image?large&space;dpi{200}sqrt[3]{frac{9x+sqrt{12+81x^2}}{18}}+sqrt[3]{frac{9x-sqrt{12+81x^2}}{18}})

as someone who has derived the solution from scratch i can confirm that it is not easy

y = x³-1

y+1 = x³

³√(y+1) = x
