sorry the equation should be
5y^2+3x^2+19=4x-2x^2-20y
Show that the equation
5y2+3x2+19=4x−2x2−20y
represents a circle by rearranging it into the centre-radius form of the equation of a circle. State the coordinates of the center and the radius of the circle.
what is the center and what is the radius??
