I don't know how I could have worked through Dorrie's version of the theorem (third listed reference on the home page) without it (it requires more blog entries than just the current page).Sheryl Tannerhttps://www.blogger.com/profile/06667411175230571539noreply@blogger.comtag:blogger.com,1999:blog-12535639.post-83436946145303683552015-09-05T07:45:06.113-07:002015-09-05T07:45:06.113-07:00E.T.

Bell tells the story of how so many people were submitting papers on quintics alleging proof or disproof of their solvability, that Gauss trashed Abel's self-printed proof when he sent it to him as "another one of those monstrosities". It fell to Crelle and his new journal to give Abel his due, which turned out to make both of them famous.<br /><br />Since that time almost 200 years ago, Abel's theorem has been validated by so many people, and so many alternative proofs have been presented of it from different angles, that it seems impossible that it could be disproven now.Sheryl Tannerhttps://www.blogger.com/profile/06667411175230571539noreply@blogger.comtag:blogger.com,1999:blog-12535639.post-5698371117816474812015-09-05T07:25:28.461-07:002015-09-05T07:25:28.461-07:00The note by Buya is incorrect.

Another way to show that the quintic does not factor as shown is to substitute a value for x into both equations. For example, with x=3 we get 241 for the quintic, but 227.5-70.1i for the product of the quadratic and cubic terms.Sheryl Tannerhttps://www.blogger.com/profile/06667411175230571539noreply@blogger.comtag:blogger.com,1999:blog-12535639.post-72765263993627373292014-01-15T05:14:41.378-08:002014-01-15T05:14:41.378-08:00consider the quintic equation x^5-x+1=0.
