x^2+8x+y^2-4y+16=0

Lösung

x^{2} + 8 x + y^{2} - 4 y + 16 = 0

Lösung

(a, b) = (- 4, 2), r = 2

Schritte zur Lösung

x^{2} + 8 x + y^{2} - 4 y + 16 = 0

Rewrite

x^{2} + 8 x + y^{2} - 4 y + 16 = 0

in the form of the standard circle equation

(x - (- 4))^{2} + (y - 2)^{2} = 2^{2}

Therefore the circle properties are:

(a, b) = (- 4, 2), r = 2

x^2+(y+sqrt(14.5^2-5^2))^2=14.5^2

x^{2} + (y + 14. 5^{2} - 5^{2})^{2} = 14. 5^{2}

x^2+5x+y^2+9y-10=0

x^{2} + 5 x + y^{2} + 9 y - 10 = 0

x^2+12x+y^2-8y+27=0

x^{2} + 12 x + y^{2} - 8 y + 27 = 0

(x-0.5)^2+(y-3.5)^2=16

(x - 0.5)^{2} + (y - 3.5)^{2} = 16

x^2+(y-6)^2=144

x^{2} + (y - 6)^{2} = 144
