x^2+y^2-4x-4y-9=0

Lösung

x^{2} + y^{2} - 4 x - 4 y - 9 = 0

Lösung

(a, b) = (2, 2), r = 17

Schritte zur Lösung

x^{2} + y^{2} - 4 x - 4 y - 9 = 0

Rewrite

x^{2} + y^{2} - 4 x - 4 y - 9 = 0

in the form of the standard circle equation

(x - 2)^{2} + (y - 2)^{2} = (17)^{2}

Therefore the circle properties are:

(a, b) = (2, 2), r = 17
