Isn't this called Newton's Sums instead of Newton sums?
Most people I know call them Newton sums, but I believe the "proper" term is Newton-Gerard Identities. --ComplexZeta 22:41, 22 August 2006 (EDT)
Question
.
How can the sum of squares equal a negative number (or does the polynomial have imaginary roots?). --Sean 17:22, 7 November 2006 (EST)
Come now, you should be able to figure that one out for yourself (especially since 1 is a root of the polynomial). --JBL 17:31, 7 November 2006 (EST)
OK, wow, stupid question. Whoooops! --Sean 22:35, 7 November 2006 (EST)
