Another option is to call S with a string::

3/2)/(2*(2*m + 1)*(2*m + 2))'
In [28]: print(S(s))
x**2*(m + 1/2)*(m + 3/2)/((2*m + 2)*(4*m + 2)) + x*(m + 1/2)/(2*m + 1) + 1

Thanks Oscar, that is a much more useful feature!
BTW, I couldn't see it mentioned in the documentation for S(), and I
think it should definitely also be mentioned in the section of of the
SymPy documentation that discusses the problem with Python evaluating
expressions like 1/2 in an unhelpful way.
