I have the circle
x^2+y^2+10x-14y-7=0
I want to find its centre and radius. In this simple case doing it by hand is probably more efficient, but is there any way to solve that in Mathematica? To use Mathematica to change x^2+y^2+10x-14y-7=0 to the formula
(x-a)^2+(y-b)^2=r^2,
where (a,b) is the centre of the circle and r is its radius? I tried the command Factor, but that did not really help.
