4x^2+4y^2+20x-8y+9=0

Lösung

4 x^{2} + 4 y^{2} + 20 x - 8 y + 9 = 0

Lösung

(a, b) = (- \frac{5}{2}, 1), r = 5

Schritte zur Lösung

4 x^{2} + 4 y^{2} + 20 x - 8 y + 9 = 0

Rewrite

4 x^{2} + 4 y^{2} + 20 x - 8 y + 9 = 0

in the form of the standard circle equation

(x - (- \frac{5}{2}))^{2} + (y - 1)^{2} = (5)^{2}

Therefore the circle properties are:

(a, b) = (- \frac{5}{2}, 1), r = 5
