Completion of the Square

I believe you want to complete the square in both x and y. If you type the equation of the circle in text form (1D math mode) then you need to include explicit multiplication, even between constants and variables. Thus, use x^2+y^2+2*x-4*y-4=0. If you enter this in math mode (2D math) then explicit multiplication will appear as a centered dot. Implied multiplication can be implemented with a space. Between a constant and a variable, you don't have to enter anything. Maple will understand that to mean multiplication.

Completion of the square is available in the Context Menu (right-click in Windows). The command upon which this is based is the CompleteSquare command in the Student[Precalculus] package. To use that command, either load the package (use the Tools menu with the Load Package option, or execute the command with(Student[Precalculus])) or issue the command in the long form: Student[Precalculus][CompleteSquare](x^2+y^2+2*x-4*y-4=0,[x,y]);
