Beliebt Geometry >

(x^2+y^2-4x-9)/4 =0

Lösung

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

Lösung

(a, b) = (2, 0), r = 13

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - 2)^{2} + (y - 0)^{2} = (13)^{2}

Therefore the circle properties are:

(a, b) = (2, 0), r = 13
