I have a complex polynomial $z^2 + 2z + 2$.

From trying out roots repeatedly I can see the correct roots are $z = -1 + i$ and $z = -1 - i$

But what is the standard method for getting roots of a complex polynomial like this?

    Depending on what you mean by "like this," I'd say the quadratic formula!2012-02-11
