Not a lot of progress... My computer died, so I will be unable to actually make the videos until I repair it or get a new one.

Who the fuck does it like that? Like seriously? Also that isn't all, you can solve by graphing and factoring and whatever Anyways, the ways I learned were ax^2+bx+c and Breathe... The formula he showed was equivalent to the one you show, and can find the zeros of all quadratics (even though there are other methods), since you can divide the equation by "a" and get the same result. If you're interested in other methods, some useful methods for finding zeros of arbitrary functions (not just quadratics) include Bisection, Secant method, and Newton-Raphson. Fixed-point methods also sometimes work, depending on the iteration function you choose. Not a lot of progress... My computer died, so I will be unable to actually make the videos until I repair it or get a new one. Ouch!

You do realize that's the same, right? But I learned to punch in the numbers into my calculator. Way faster.

Yeah it's the same but the letters aren't alphabetical and it's written a little different so meh
