What is the best way to find the roots of polynomials in Julia?

I would normally (i.e. unless there is something very special about your polynomials) use Polynomials.jl: [https://github.com/JuliaMath/Polynomials.jl](https://github.com/JuliaMath/Polynomials.jl)

There is also [https://github.com/giordano/PolynomialRoots.jl](https://github.com/giordano/PolynomialRoots.jl) if all you need is roots, it’s faster
