x^2+y^2-8x+4y-10=0

Lösung

x^{2} + y^{2} - 8 x + 4 y - 10 = 0

Lösung

(a, b) = (4, - 2), r = 30

Schritte zur Lösung

x^{2} + y^{2} - 8 x + 4 y - 10 = 0

Rewrite

x^{2} + y^{2} - 8 x + 4 y - 10 = 0

in the form of the standard circle equation

(x - 4)^{2} + (y - (- 2))^{2} = (30)^{2}

Therefore the circle properties are:

(a, b) = (4, - 2), r = 30

(x-6)^2+(y+1)^2=4

(x - 6)^{2} + (y + 1)^{2} = 4

(x-7)^2+(y+5)^2=4

(x - 7)^{2} + (y + 5)^{2} = 4

8 x^{2} + 8 y^{2} = 32

4x^2+4x+4y^2-24y-27=0

4 x^{2} + 4 x + 4 y^{2} - 24 y - 27 = 0

(y^2)/2 =-(x^2)/2+2

\frac{y ^{2}}{2} = - \frac{x ^{2}}{2} + 2
