Interesting. Can you try the following (which actually does work for me):
---------------------------------------------------------------------- | Sage Version 4.0, Release Date: 2009-05-29 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: poly = x^2+x+1 sage: def myroots(p): ....: R = IntegerModRing(p) ....: RR.<t> = R[] ....: f = RR(poly(x=t)) ....: return f.roots(R) ....: sage: myroots(7) [(4, 1), (2, 1)] If this doesn't work for you, can you give more details (which version of Sage are you using, are you working in the command line or the notebook).
