Hey everyone(adsbygoogle = window.adsbygoogle || []).push({});

Im doing control engineering and was wondering what methods i could use to find the roots of a 4th order polynomial?

For example:

(x^4) + (8x^3) + (7x^2) + 6x = 5

Could I seperate that into two brackets of quadratics or will i need to use a really long winded method?

Thanks in advance for any help
