4x^2+4y^2-20x+40y=-5

Lösung

4 x^{2} + 4 y^{2} - 20 x + 40 y = - 5

Lösung

(a, b) = (\frac{5}{2}, - 5), r = 30

Schritte zur Lösung

4 x^{2} + 4 y^{2} - 20 x + 40 y = - 5

Rewrite

4 x^{2} + 4 y^{2} - 20 x + 40 y = - 5

in the form of the standard circle equation

(x - \frac{5}{2})^{2} + (y - (- 5))^{2} = (30)^{2}

Therefore the circle properties are:

(a, b) = (\frac{5}{2}, - 5), r = 30
