 * Aim:** How do we find a specific term of a binomial expansion?

At the end of the lesson, you will be able to...
 * 1) determine the middle term of an expanded binomial by using the Binomial Theorem
 * 2) determine a specific term of an expanded binomial by using the Binomial Theorem

Answer the following questions as you watch the videos: 1. What is the rule for finding the specific term of a binomial expansion? 2. Write the formula to find the specific term of a binomial expansion.
