x^2+y^2-8x-4y-61=0

Lösung

x^{2} + y^{2} - 8 x - 4 y - 61 = 0

Lösung

(a, b) = (4, 2), r = 9

Schritte zur Lösung

x^{2} + y^{2} - 8 x - 4 y - 61 = 0

Rewrite

x^{2} + y^{2} - 8 x - 4 y - 61 = 0

in the form of the standard circle equation

(x - 4)^{2} + (y - 2)^{2} = 9^{2}

Therefore the circle properties are:

(a, b) = (4, 2), r = 9

(x-5)^2+(y+3)^2=16

(x - 5)^{2} + (y + 3)^{2} = 16

x^2+y^2+4x+8y+16=0

x^{2} + y^{2} + 4 x + 8 y + 16 = 0

X^{2} + Y^{2} = 16

-11=-4y^2-4y-4x^2

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

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

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