center x^2+y^2+2x-4y-15=0

Lösung

center

x^{2} + y^{2} + 2 x - 4 y - 15 = 0

Lösung

(- 1, 2)

Schritte zur Lösung

x^{2} + y^{2} + 2 x - 4 y - 15 = 0

Rewrite

x^{2} + y^{2} + 2 x - 4 y - 15 = 0

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 2)^{2} = (25)^{2}

Therefore the circle properties are:

(a, b) = (- 1, 2), r = 25

And the center is:

(- 1, 2)
