# Algebra 2 Binomial Theorem

If you expand a binomial, you get certain coefficients. The coefficients of the terms can be used to create an array of numbers called Pascal's triangle. There are some properties that the expansion of (a+b)^n satisfies, and you’ll learn about them in this lesson. This lesson also covers factorials, and the binomial formula. The coefficients of the expansion are symmetrical around the middle term. So once you have found the first half of the coefficients, you already have the coefficients for the rest of the terms. They are the same ones you have found but listed in reverse order.
