X2 + y2 -2x + 24y +120 = 0 Find the center and radius of this circle by converting it to (x-h)2 + (y-k)2 =r2

r=5  O(1;-12)

Step-by-step explanation:

x² + y² -2x + 24y +120 = 0

⇒ x²-2x+1+ y²+ 24y+144-145+120 = 0

⇒ (x-1)²+ (y+12)²=25   and    (x-h)² + (y-k)² =r²

so, h=1          k=-12       r=√25=5

center is O(h;k)   O(1;-12)

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
