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)
