4x^2+20x+4y^2-24y+21=0

Lösung

4 x^{2} + 20 x + 4 y^{2} - 24 y + 21 = 0

Lösung

(a, b) = (- \frac{5}{2}, 3), r = 10

Schritte zur Lösung

4 x^{2} + 20 x + 4 y^{2} - 24 y + 21 = 0

Rewrite

4 x^{2} + 20 x + 4 y^{2} - 24 y + 21 = 0

in the form of the standard circle equation

(x - (- \frac{5}{2}))^{2} + (y - 3)^{2} = (10)^{2}

Therefore the circle properties are:

(a, b) = (- \frac{5}{2}, 3), r = 10
