General formulae for Roots of 5 degree polynomial

Question

I have found roots for 4 order polynomial but for 5th order Wolfram mathematicia is showing this kind of solution which is not readable enter image description here

Answer 1

I've no idea what Wolfram Alpha is trying to say here. There is no formula for the roots of the general fifth degree polynomial.

Solving quintic equations in terms of radicals (nth roots) was a major problem in algebra from the 16th century, when cubic and quartic equations were solved, until the first half of the 19th century, when the impossibility of such a general solution was proved with the Abel–Ruffini theorem.
