The equation of the circle in squared form is [tex]\rm (x + 6)^2 + (y + 1)^2 = 38[/tex]. Then the center of the circle is at (-6, -1).
What is a circle?
It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
[tex]\rm x^{2} + y^2 + 12x +2y - 1 = 0[/tex]
This can be written as
[tex]\rm x^{2} + y^2 + 12x +2y = 1[/tex]
Add both sides 36 and 1, then
[tex]\rm x^{2} + 12x + 36 + y^2 +2y +1 = 1 + 36 + 1[/tex]
Then we know that
[tex]\rm (a+b) ^2 = a^2 + b^2 + 2ab[/tex]
Then
[tex]\rm (x + 6)^2 + (y + 1)^2 = 38[/tex]
Thus, the center of the circle is at (-6, -1).
