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.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

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

By the power of the exponent, I square and cube you! cool

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.
