Comment #48 on issue 1694 by nicolas.pourcelot: solve has many issues with
fractions
http://code.google.com/p/sympy/issues/detail?id=1694
Hmm... There's something I can't explain for now.
After patch:
from sympy import *
var('x')
x
eq=x**Rational(1,2)+x**Rational(1,3)+x**Rational(1,4)
ans=solve(eq,x)
[checksol(eq,x,a) for a in ans]
[False, True, False]
So, bad solutions are detected by checksol(), but not removed. :-/
I feel definitively sleepy, I'll looked at this tomorrow...
