The given equation is written in the general form of the equation of a circle:
To find the center and radius, we need to write the equation in the standard form:
Where (h,k) are the coordinates of the center and r is the radius.
The first step is to complete the perfect square trinomials:
Where a and b are the numbers we need to find to complete the perfect square trinomials, so:
Apply the same procedure for the next perfect square:
Now, we know a=5 and b=1, let's rewrite the equation:
This equation is in the standard form, so:
