Answer:
Step-by-step explanation:
The standard form equation of a circle is ...
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r
Divide your given equation by 2 to put it into standard form:
(x +3)^2 +y^2 = 16
Comparing to the above, we see ...
The center point of the circle is (-3, 0); the radius is 4 units long.
