Before of this patch, this calculation returned an AssertionError
(see issue #1051).
Adopted approach is to not use the assumptions framework for this
calculation. This is faster, but also, since we are slowly moving
the assumption system out of the core, this will have to be how
things are done
I've added a new functions.txt file to document sympy.function module,
and also added docstrings to functions that did not have one.
However most of the functions documented in the functions.txt file
are simply references to the docstrings. Someday this
should be expanded with examples and

Since no cubics of quartics formula is used in the determination of rational
roots and the algorithm is fast, rational roots are first computed for all
polynomials. In some cases this also reduces the degree of the polynomial, thus
solving polynomials

Nice work!
Couple of questions: what does zzx stand for?
Wouldn't this be the case (lot's of functions with the same prefix)
where you should use a class and the methods should be static methods
(instead of using prefixes all the time)?

But then Rational(1.) == Integer(1)
and that is not only ugly but incorrect ...
A solution would be to check if int(p) == p.
yeah, that would be a nice solution, but I think that accepting float's as
arguments is
working on my mac ... (not to say windows users!)
