Find the center and radius of the circle using the equation:

x^2 + y^2 + 2√2x - 4√5y = 5

I just cant seem to solve this equation into the form (x-h)^2 + (y-k)^2 = r^2 in order to get the center and radius.

Any help would be appreciated

You would need to show us what you have tried. First thing you do is group up the terms and complete the square.
