x^2+y^2-8x+4y+18=0

Lösung

x^{2} + y^{2} - 8 x + 4 y + 18 = 0

Lösung

(a, b) = (4, - 2), r = 2

Schritte zur Lösung

x^{2} + y^{2} - 8 x + 4 y + 18 = 0

Rewrite

x^{2} + y^{2} - 8 x + 4 y + 18 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (4, - 2), r = 2

(x+3)^2+(y+5)^2=100

(x + 3)^{2} + (y + 5)^{2} = 100

(x-1)^2+(y+5)^2=4

(x - 1)^{2} + (y + 5)^{2} = 4

(x-3)^2+(y-5)^2=5^2

(x - 3)^{2} + (y - 5)^{2} = 5^{2}

\frac{x ^{2} + y ^{2}}{9} = 1

x^2+y^2+2x+4y=11

x^{2} + y^{2} + 2 x + 4 y = 11
