Your message is somewhat cryptic. Presumably you want to learn
something about Abel's work on the insolubility by radicals of
the general fifth degree polynomial equation.

A biographical approach is here:

[Niels Henrik Abel (1802-1829)]
http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Abel.html

An appreciation of Abel's work, as distinct from Galois's, must
start with the earlier work of Ruffini, who published a book in
1799 with the title:

General theory of equations in which it is shown that the
algebraic solution of the general equation of degree greater
than four is impossible

[Paolo Ruffini (1765-1822)]
http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Ruffini.html

From a modern perspective it may be said that Ruffini's work
contains a gap. However his real problem with it was perhaps
that it was ahead of its time and attracted little if any
critical attention by other mathematicians, with the arguable
exception of Cauchy.
