center x^2+y^2-12x+20y+15=0

center

x^{2} + y^{2} - 12 x + 20 y + 15 = 0

(6, - 10)

Solution steps

x^{2} + y^{2} - 12 x + 20 y + 15 = 0

Rewrite

x^{2} + y^{2} - 12 x + 20 y + 15 = 0

in the form of the standard circle equation

(x - 6)^{2} + (y - (- 10))^{2} = 1 1^{2}

Therefore the circle properties are:

(a, b) = (6, - 10), r = 11

And the center is:

(6, - 10)

x^{2} + y^{2} = \frac{1}{4}

x^{2} + y^{2} - 2 x + 6 y - 15 = 0

4 x^{2} - 4 x + 4 y^{2} - 63 = 0

(x - 3)^{2} + (y + 4)^{2} = 25

x^{2} + y^{2} - 8 x + 12 y = - 43

What is the center x^2+y^2-12x+20y+15=0 ?
The center x^2+y^2-12x+20y+15=0 is (6,-10)
