x^2+y^2+8x+2y+9=0

Lösung

x^{2} + y^{2} + 8 x + 2 y + 9 = 0

Lösung

(a, b) = (- 4, - 1), r = 22

Schritte zur Lösung

x^{2} + y^{2} + 8 x + 2 y + 9 = 0

Rewrite

x^{2} + y^{2} + 8 x + 2 y + 9 = 0

in the form of the standard circle equation

(x - (- 4))^{2} + (y - (- 1))^{2} = (22)^{2}

Therefore the circle properties are:

(a, b) = (- 4, - 1), r = 22

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

((2x-2)^2)/2+((2y+6)^2)/2 = 46/2

\frac{( 2 x - 2 ) ^{2}}{2} + \frac{( 2 y + 6 ) ^{2}}{2} = \frac{46}{2}

x^2+y^2-2x-8y+1=0

x^{2} + y^{2} - 2 x - 8 y + 1 = 0

(x-5)^2+(Y(x)+2)^2=16

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

2x^2+12x+2y^2-2y-3=0

2 x^{2} + 12 x + 2 y^{2} - 2 y - 3 = 0
