Talk:Vieta jumping

Vieta jumping newness
The claim that "Vieta jumping is a relatively new technique in solving mathematical olympiad problems" is bogus and not supported by the references. Engel certainly doesn't say anything like that. Vieta jumping appears, for example, in Gauss' Disquisitiones Arithmeticae.EarlyMorningOwl (talk) 02:47, 22 November 2020 (UTC) A readily available reference, later than Gauss but earlier than the use in competitions, could be this article by Hurwitz. — Preceding unsigned comment added by EarlyMorningOwl (talk • contribs) 02:51, 22 November 2020 (UTC)

Duplicate example
The example of the problem #6 at IMO 1988 appears in the article twice; one example should be enough. Bronx (talk) 09:05, 6 August 2022 (UTC)
