center 2x^2+2y^2-12x+4y-30=0

center

(3, - 1)

Solution steps

2 x^{2} + 2 y^{2} - 12 x + 4 y - 30 = 0

Rewrite

2 x^{2} + 2 y^{2} - 12 x + 4 y - 30 = 0

in the form of the standard circle equation

(x - 3)^{2} + (y - (- 1))^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (3, - 1), r = 5

And the center is:

(3, - 1)
