Algorithms like factor can handle algebraic numbers using the extension flag
In [182]: factor(x**2 + 1, extension=[I]) Out[182]: (x - ⅈ)⋅(x + ⅈ) In general, algebraic numbers can be slow, because minpoly is slow (this is being fixed at https://github.com/sympy/sympy/pull/2038). I think multiple extensions are also slow for other reasons. Currently, only algebraic numbers are supported, but it would be great to support algebraic functions (like sqrt(x) instead of sqrt(2)).
