find the center and radius of this circle?

Question

x^2+y^2-6x-10y+30=0

Answer 1

x² + y² - 6x - 10y + 30 = 0

x² + y² - 6x - 10y = - 30        subtract 30 from both sides

x² - 6x     + y² - 10y = - 30    group variables.

x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25        complete the square

 

Can you put into graphing form?
