The standard equation of a circle with center C(h,k) and radius r is as follows:
(x - h)2 + (y - k)2 = r2
We have...
x2 + y2 - 10x + 8y + 5 =0
x2 - 10x + y2 + 8y + 5 =0
add h2 and k2 to both sides
(x2 - 10x + h2) + (y2 + 8y + k2) = -5 + h2 + k2
Using the above framework we can see that 10 = 2h, h = 5
Using the above framework we can see that 8 = 2k, k = 4
So the formula is
(x2 - 10x + 25) + (y2 + 8y + 16) = -5 + 25 + 16
(x - 5)2 + (y - 4)2 = 36
the center of the circle is C(5,4) and radius 6
