center x^2+y^2-2x+3y-1=0

center

x^{2} + y^{2} - 2 x + 3 y - 1 = 0

(1, - \frac{3}{2})

Solution steps

x^{2} + y^{2} - 2 x + 3 y - 1 = 0

Rewrite

x^{2} + y^{2} - 2 x + 3 y - 1 = 0

in the form of the standard circle equation

(x - 1)^{2} + (y - (- \frac{3}{2}))^{2} = (\frac{17}{2})^{2}

Therefore the circle properties are:

(a, b) = (1, - \frac{3}{2}), r = \frac{17}{2}

And the center is:

(1, - \frac{3}{2})

x^{2} + y^{2} - 4 x + 6 y + 9 = 0

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

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

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

2 x^{2} + 2 y^{2} = 18
