5x^2+5y^2+10x+2y+3=0

5 x^{2} + 5 y^{2} + 10 x + 2 y + 3 = 0

(a, b) = (- 1, - \frac{1}{5}), r = \frac{11}{5}

Solution steps

5 x^{2} + 5 y^{2} + 10 x + 2 y + 3 = 0

Rewrite

5 x^{2} + 5 y^{2} + 10 x + 2 y + 3 = 0

in the form of the standard circle equation

(x - (- 1))^{2} + (y - (- \frac{1}{5}))^{2} = (\frac{11}{5})^{2}

Therefore the circle properties are:

(a, b) = (- 1, - \frac{1}{5}), r = \frac{11}{5}

x^{2} + y^{2} = 169

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

x^{2} + (y - 3)^{2} = 9

3 x^{2} + 3 y^{2} - 6 x + 12 y = 0

x^{2} + y^{2} + 8 x - 14 y - 56 = 0
