I need help solving for B in this equation:

(NOTE: 5b^2 is 5b squared)

5b^2 - 5b +1 = 0

I started by subtracting -1 from both sides getting:

5b^2 - 5b = -1

Then I pulled out 5b from the left side and got:

5b (b - 1) = -1

And now I have no idea what to do. I think I am doing the entire thing wrong. Can someone help me out?
