9x^2+9y^2+42x-54y+49=0

Lösung

9 x^{2} + 9 y^{2} + 42 x - 54 y + 49 = 0

Lösung

(a, b) = (- \frac{7}{3}, 3), r = 3

Schritte zur Lösung

9 x^{2} + 9 y^{2} + 42 x - 54 y + 49 = 0

Rewrite

9 x^{2} + 9 y^{2} + 42 x - 54 y + 49 = 0

in the form of the standard circle equation

(x - (- \frac{7}{3}))^{2} + (y - 3)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- \frac{7}{3}, 3), r = 3

(x-7/4)^2+(y+3/4)^2= 169/16

(x - \frac{7}{4})^{2} + (y + \frac{3}{4})^{2} = \frac{169}{16}

(x-2)^2+(y-1)^2=16

(x - 2)^{2} + (y - 1)^{2} = 16

x^{2} + y^{2} = 72

x^{2} + y^{2} \leq 9

x^2+y^2-4x+6y-3=0

x^{2} + y^{2} - 4 x + 6 y - 3 = 0
