Comment #6 on issue 2236 by [email protected]: solve fails for polysys with
multiple solutions
http://code.google.com/p/sympy/issues/detail?id=2236
The original system, rational system (nsimplify(eq, rational=True)), and
the primitive form of the equations 9with no denominators) all hang in
polys now. With the new solver in place, only these two equations are being
passed along:
[Poly(200*x**2*a0 - x**2 - 400*x*a0 + 800*y + 400*lam, x, y, a0,
domain='ZZ[lam]
'),
Poly(-50000000000000*x**2*a0 + 100000000000000*x*a0 - 174343670091673*y, x,
y, a0, domain='ZZ'), Poly(x + y - conc, x, y, a0, domain='ZZ[conc]')]
Having extra symbols besides those being sought is not the problem since
solutions for the following are obtained:
solve((x**2-y+b,x**2-y**2+z),x,y)
