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

Lösung

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

Lösung

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

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

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

5 x^{2} + 5 y^{2} - 4 x + y - 3 = 0

x^2+y^2+6x-8y-10=0

x^{2} + y^{2} + 6 x - 8 y - 10 = 0

3^2=(x-0)^2+(y+2)^2

3^{2} = (x - 0)^{2} + (y + 2)^{2}

(x-2)^2+(y+3)^2=3

(x - 2)^{2} + (y + 3)^{2} = 3

4 x^{2} + 4 y^{2} = 256
