I get different results: In [1]: p1, p2 = [(x - 5)**2 + (y - 5)**2 - 4, -(-x + 5)*(-x - 2*2**(1/S(2)) + 5) - (-y + 5)*(-y + 5)] In [2]: p1.as_poly(x, y, extension=True) Out[2]: Poly(x**2 - 10*x + y**2 - 10*y + 46, x, y, domain='ZZ') In [3]: p2.as_poly(x, y, extension=True) Out[3]: Poly(-x**2 + (-2*2**(1/2) + 10)*x - y**2 + 10*y - 50 + 10*2**(1/2), x, y, domain='QQ<2**(1/2)>') > -- > You received this message because you are subscribed to the Google Groups > "sympy" group. > To post to this group, send email to sympy@googlegroups.com. > To unsubscribe from this group, send email to > sympy+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/sympy?hl=en. > Mateusz -- You received this message because you are subscribed to the Google Groups "sympy" group.
