Weird Circle Equation (1 Viewer)

[Heresy]

Here it is:

Find the coordinates of the centre and find the radius of a circle with an equation of:

x^2 + 8x + y^2 - 6y

I haven't seen a circle equation like this, so I am confused. Any response would be appreciated.

You have to complete the square and you get centre (-4,3) and radius 5

Thank you so much!
