4x^2+4y^2-4x+2y-1=0

Lösung

4 x^{2} + 4 y^{2} - 4 x + 2 y - 1 = 0

Lösung

(a, b) = (\frac{1}{2}, - \frac{1}{4}), r = \frac{3}{4}

Schritte zur Lösung

4 x^{2} + 4 y^{2} - 4 x + 2 y - 1 = 0

Rewrite

4 x^{2} + 4 y^{2} - 4 x + 2 y - 1 = 0

in the form of the standard circle equation

(x - \frac{1}{2})^{2} + (y - (- \frac{1}{4}))^{2} = (\frac{3}{4})^{2}

Therefore the circle properties are:

(a, b) = (\frac{1}{2}, - \frac{1}{4}), r = \frac{3}{4}
