x^2-1x+y^2-3y-20=0

x^{2} - 1 x + y^{2} - 3 y - 20 = 0

(a, b) = (\frac{1}{2}, \frac{3}{2}), r = \frac{3 5}{2}

Solution steps

x^{2} - 1 \cdot x + y^{2} - 3 y - 20 = 0

Rewrite

x^{2} - 1 x + y^{2} - 3 y - 20 = 0

in the form of the standard circle equation

(x - \frac{1}{2})^{2} + (y - \frac{3}{2})^{2} = (\frac{3 5}{2})^{2}

Therefore the circle properties are:

(a, b) = (\frac{1}{2}, \frac{3}{2}), r = \frac{3 5}{2}
