Quartic formula

For the general quartic:

You never see the 4 roots of a quartic given in terms of its coefficients. Here it is:

The roots now are:


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Quartic formula

It seems impractical to remember it, but it is a nice formula..

Re: Quartic formula

It is for reference only. There are numerical means that are superior. I just had fun with the derivation.

Re: Quartic formula

Quartic formula? I thought it was a quadratic formula. Or are they different? dunno

Re: Quartic formula

Quartic formula is very different, see post #1.

The quadratic formula solves quadratics, the quartic, quartics.

Re: Quartic formula

Yup. That is way out of the range.
