4x^2-8x+4y^2+28y=11

Lösung

4 x^{2} - 8 x + 4 y^{2} + 28 y = 11

Lösung

(a, b) = (1, - \frac{7}{2}), r = 4

Schritte zur Lösung

4 x^{2} - 8 x + 4 y^{2} + 28 y = 11

Rewrite

4 x^{2} - 8 x + 4 y^{2} + 28 y = 11

in the form of the standard circle equation

(x - 1)^{2} + (y - (- \frac{7}{2}))^{2} = 4^{2}

Therefore the circle properties are:

(a, b) = (1, - \frac{7}{2}), r = 4
