x^2-2x+y^2+4y-11=0

Lösung

x^{2} - 2 x + y^{2} + 4 y - 11 = 0

Lösung

(a, b) = (1, - 2), r = 4

Schritte zur Lösung

x^{2} - 2 x + y^{2} + 4 y - 11 = 0

Rewrite

x^{2} - 2 x + y^{2} + 4 y - 11 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (1, - 2), r = 4

(y^2)/(3.58^2)+(x^2)/(3.58^2)=1

\frac{y ^{2}}{3.5 8 ^{2}} + \frac{x ^{2}}{3.5 8 ^{2}} = 1

8^{2} = a^{2} + b^{2}

(x-1)^2+(y-(-3))^2=6.7^2

(x - 1)^{2} + (y - (- 3))^{2} = 6. 7^{2}

2x^2+2y^2+12x-28y+104=0
