4x^2+4y^2+8x-16y+11=0

Lösung

4 x^{2} + 4 y^{2} + 8 x - 16 y + 11 = 0

Lösung

(a, b) = (- 1, 2), r = \frac{3}{2}

Schritte zur Lösung

4 x^{2} + 4 y^{2} + 8 x - 16 y + 11 = 0

Rewrite

4 x^{2} + 4 y^{2} + 8 x - 16 y + 11 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- 1, 2), r = \frac{3}{2}
