Needs Answer
Hi all,
I was hoping there might be some CAS function that could convert, eg. x²+y²-4x+8y-5=0 into the form (x-2)²+(y-4)²=25. Geogebra can clearly handle the interchange internally, since it is possible to view the equation of the circle in either form, but I would really like to know if there is a way of 'persuading' Geogebra's CAS to display the completed-square version instead of the expanded form.
Many thanks,
Pi.
