Answer:
The center of the circle would be the point (-10,4).
Step-by-step explanation:
When an equation for a circle is written in the center-radius form, it makes it easier to tell where the center will lie.
The traditional equation for a circle is (x-h)²+(y-k)²=r², with the center of (h,k) and a radius of r, can be applied to this situation. Since the given equation has a value added to the x within the parentheses, the formula tells us that it must be a negative point, so we have x=-10. Similarly we can easily pull out the y-coordinate which would just be 4.
Thus, the answer is (-10,4).
