I have NO idea. You guys?

You wrote it by some unusual way. Try this:

Looks like advanced algebra, but definitely has something to do with data because of the â. Maybe graph theory?

It's the binomial theorem, from probability/statistics.
In easier language:
(a + b)^n
= nC0(a^(n-0))(b^0) + nC1(a^(n-1))(b^1) + ... + nC(n - 1)(a^(n-(n - 1)))(b^(n-1)) + nCn(a^(n - n))(b^n)

It's the basis of integrating functions
