status is really about 2.5 - 2 for the elementary binomial theorem/formula, and 3 for the Newtonian. Anthony Argyriou 17:23, 18 July 2007 (CDT)


While the definition is strictly true, it seems written backwards, in that if you actually do the sum for (x+y)^2 the answer you get as the equation is written is y^2 + 2xy + x^2. Of course you can rearrange to get x^2 + 2xy + y^2. Another way to write it would be

x^(n-k)y^(k), in which case you directly get the answers as shown in the examples.

Can we get rid of the In popular culture section? It adds nothing to anyone's understanding of the binomial theorem. Anthony Argyriou 11:02, 15 July 2008 (CDT)
