Find the center and radius for the circles with the following equation x^2+y^2-4x+6y+11=0

Rearrange x²+y²-4x+6y=-11 I'll tell you an easy way. take the coefficient of x and divide it by - 2 and the coefficient of y and divide it by - 2 so - 4 : - 2 = 2 6:-2 = - 3 (2,-3) is the center of the circle to know the radius √2² + - 3² + - 11 = √2 The Radius equals √2
