The coefficients that appear in the binomial expansion are called binomial coefficients. These are usually written and pronounced "n choose k". The coefficient of x y is given by the formula The binomial coefficient can be interpreted as the number of ways to choose k elements from an n-element set. This is related to binomials for the following reason: if we write (x + y) as a product WebThe Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand expressions like this directly. But with the Binomial theorem, the process is relatively fast! Created by Sal Khan.
