New issue 1897 by [email protected]: solve and Real
http://code.google.com/p/sympy/issues/detail?id=1897
solve has some problems with Real in current master branch.
example:
f = Rational(2,3)+Rational(345/21)*x+Rational(2394/13)*x**2
solve(f,x)
[-221/55062 - I*10926851**(1/2)/55062, -221/55062 + I*10926851**
(1/2)/55062]
solve(f.evalf(),x)
Traceback (most recent call last):
