# Binomial Theorem

Pronunciation: /baɪˈnoʊ.mi.əl ˈθiər.əm/ Explain

The binomial theorem states that when raising a binomial to an integer power, the binomial coefficients can be calculated using the combination

where n is the integer power, and k is the order of the coefficient.[2] This is expressed mathematically with the expression
In this expression
So the first term is
The next two terms are
and
This gives a result of
You can use long multiplication to verify this result.
