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

Lösung

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

Lösung

(a, b) = (4, - 1), r = 5

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (4, - 1), r = 5

9x^2-42x+9y^2+84y+65=0

9 x^{2} - 42 x + 9 y^{2} + 84 y + 65 = 0

{x-(-3)}^2+{y-(-4)}^2=1

{x - (- 3)}^{2} + {y - (- 4)}^{2} = 1

(x-5)^2+(y+2)^2=7.5

(x - 5)^{2} + (y + 2)^{2} = 7.5

x^2+(y-7.5)^2= 9/49

x^{2} + (y - 7.5)^{2} = \frac{9}{49}

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

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