x^2+8y+y^2+7=0

Lösung

x^{2} + 8 y + y^{2} + 7 = 0

Lösung

(a, b) = (0, - 4), r = 3

Schritte zur Lösung

x^{2} + 8 y + y^{2} + 7 = 0

Rewrite

x^{2} + 8 y + y^{2} + 7 = 0

in the form of the standard circle equation

(x - 0)^{2} + (y - (- 4))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (0, - 4), r = 3

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

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

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

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

(x^2+(-10)x+25)+(y^2+9y+81/4)=-1+25+81/4

(x^{2} + (- 10) x + 25) + (y^{2} + 9 y + \frac{81}{4}) = - 1 + 25 + \frac{81}{4}

x^2+6x+y^2-2y-26=0

x^{2} + 6 x + y^{2} - 2 y - 26 = 0

x^2+y^2+9x-10=0

x^{2} + y^{2} + 9 x - 10 = 0
