**[SOLVED] How would one factor this.. by hand..**

Assuming I didn't know the perfect square formula ( (a+-b)^2), how would I go about solving this equation by hand factoring?

x^2 + b/a *x + b^2 / 4a^2 = 0

I am trying to figure out how the quadratic formula is derived, and this is one part of deriving the equation in which I am unable to hand factor(assuming I didn't know perfect squares formula), how would one go about doing this ?

It is included on a website(step 3 and 4), http://www.1728.com/quadr2.gif" [Broken]

Can someone show me the steps to factoring that by hand?
