The center is:
(2, -4)
Step-by-step explanation:
We have the following equation
The general equation of a circle has the following form
Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1
Step 2
Add and subtract
For an equation of the form
Step 3 Factor the expressions within the parentheses
Step 4 Simplify
Finally
The center is:
(2, -4)
