The graph of x^2 - 2x + y^2 = 24 is a circle. Find the center and radius of this circle.

We can use the circle equation:\((x-h)^2+(y-k)^2=r^2\),\(h=\)x of center,\(k=\)y of the center

 

so \(x^2-2x+y^2=24\) Is now more clearer because if \((h=-1,k=0),(x-1)^2+(y)^2=5^2\)simplified is:

 

The middle:\((-1,0)\), the raidius \(r=5\)
