Sage is a mathematical software system, and this tag is intended for questions involving this software in a substantive way. This tag should hardly ever be the only tag of a question; typically there should be additional tags to indicate the mathematical content of the question. Please note that questions that are purely support-questions on Sage are not a good fit for this site.

Computation of a minimal polynomial
In Sage you can do something like:
x=polygen(QQbar)
f=x^5 - x +1
roots = f.roots(QQbar)
a1 = roots[1][0]
a2 = roots[-1][0]
(a1 - a2).minpoly()
x^20 - 10*x^16 - 95*x^12 + 625*x^10 - 40*x^8 + 3750*x^6 + …
