Factor to complex roots using sympy

2024/4/15 0:52:15

I can't figure out how to factor an polynomial expression to its complex roots.

>>> from sympy import *
>>> s = symbol('s')
>>> factor(s**2+1)2
s  + 1
Answer

You need to add I as an algebraic extension:

In [2]: factor(x**2 + 1, extension=[I])
Out[2]: (x - ⅈ)⋅(x + ⅈ)
