Re: I discovered a new formula to solve 2 degree equations

at least this could be a new way to solve a second degree equations, it could be easier for some equations, (like matrices, sometimes Kramer's rule is easier than the augmented matrices) if that is useful to you, use it, it is always good to try to find something new.

I notice that, while 'factoring' and "the quadratic formula" have been mentioned, no one has mentioned "completing the square". That works when "factoring" doesn't and is how one derives the quadratic formula.
