4x^2+4y^2-8x+8y-28=0

Lösung

4 x^{2} + 4 y^{2} - 8 x + 8 y - 28 = 0

Lösung

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

Schritte zur Lösung

4 x^{2} + 4 y^{2} - 8 x + 8 y - 28 = 0

Rewrite

4 x^{2} + 4 y^{2} - 8 x + 8 y - 28 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

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