    The quadratic formula is neat! The (informal) proof is very neat also. If you remember back to completing the square...

    Let ax^2 + bx + c = 0 be a binomial function where a,b,c are all real numbers. Then
    x^2 + (b/a)x + c/a = 0
    -> [x + b/(2a)]^2 - [b/(2a)]^2 + c/a = 0
    -> [x + b/(2a)]^2 = [b/(2a)]^2 - c/a
    -> [x + b/(2a)]^2 = b^2 / (4a^2) - 4ac / (4a^2)
    -> [x + b/(2a)]^2 = (b^2 - 4ac) / (2a)^2
    -> x + b/(2a) = +/-sqrt[(b^2 - 4ac) / (2a)^2]
    -> x = - b/(2a) +/- sqrt(b^2 - 4ac) / 2a
    -> x = [- b +/- sqrt(b^2 - 4ac)] / 2a

    Tadaaaa!

    Yeah, completing the square on the quadratic equation really helps you understand why the formula is what it is! Afro

    Remove these maths from this thread immediately. I have used the formulas in the past week enough to make me throw up at the mere talk of them.

    Just like Johnny Flynn said, the breath I've taken and the one I must to go on.

    As an alternative, you can multiply through by 4a.

    ax^2 + bx +c =0     (a≠0)

    • 4a^2 x^2 +4abx +4ac =0
    • 4a^2 x^2 +4abx = (2ax+b)^2 - b^2
    • (2ax+b)^2 - b^2 +4ac =0
    • (2ax+b)^2 = b^2 -4ac
    • 2ax+b = ±√(b^2-4ac)

    Therefore:



    Imo, this version is slightly less messy.

    So that's why lua crossed the road?

    `But I don't want to go among mad people,' Alice remarked.
     `Oh, you can't help that,' said the Cat: `we're all mad here. I'm mad.  You're mad.'
     `How do you know I'm mad?' said Alice.
     `You must be,' said the Cat, `or you wouldn't have come here.'

    Well, C(1000000000000,1) doesn't make much sense in this context, but I'll answer anyways.



    See:

    For nicer explanations.

    Why did I not see this until now? I agree, that is much neater!
