Beliebt Geometry >

x^2-2x+1+y^2+4y+4=25

Lösung

x^{2} - 2 x + 1 + y^{2} + 4 y + 4 = 25

Lösung

(a, b) = (1, - 2), r = 5

Schritte zur Lösung

x^{2} - 2 x + 1 + y^{2} + 4 y + 4 = 25

Rewrite

x^{2} - 2 x + 1 + y^{2} + 4 y + 4 = 25

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (1, - 2), r = 5
