Can someone help me out and go through the steps for how to complete the square for this problem? I can never quite figure it out.

The problem is: $\displaystyle x^2-6x-1=0$ Then I know I would want to switch it to:$\displaystyle x^2-6x=1$ Normally I know I would divide everything by what is in front of the x, but in that case it's nothing (1), and dividing by 1 obviously wouldn't do anything. So what else do I need to do?

thanks
