What's wrong with :
sage: prod([(x-t[0])^t[1] for t in (x^2-26*x-9).roots(x)])
(x + sqrt(178) - 13)*(x - sqrt(178) - 13)
which stays in SR ?

First of all, what you create is a symbolic function, so, factorisation
doesn't really make sense.
sage: g(x) = x^2-26*x-9
sage: g
x |--> x^2 - 26*x - 9
What you probably want t
