Thanks a lot 2017-10-07 13:46:00 -0500 asked a question Get the constant value of an equation 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() function doesn't work for constant so I have no idea to get the constant value. 2017-10-07 13:46:00 -0500 asked a question Get the coefficient of the constant 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.
