I have the following equation :

(x - 1)^2 - (x - 2)^2 - (y - 1)^2 + y^2 + (z - 3)^2 - (z - 4)^2 == 1.75000000000000

which I factorized to :

2*x + 2*y + 2*z - 51/4

And then I would like to extract the -51/4 but the .coefficient() doesn't work for constant so I have no idea to get the constant value.
