Binomial expansion what is constant term

Finding the constant term in a binomial expansion usually is taught concurrently with how to find the greatest co-efficient. Once again, depending on your students and their learning style, you can utilise a flip learning model for this content. There are some great teaching resources available via YouTube, which clearly demonstrate to students what and how they are to approach questions relating to finding the constant term in a binomial expansion.

This will be intuitive for most students, as they will know that it is the last term. Then, ask them what the constant term in the following binomial expansion will be:. Once you are satisfied with the discussions, show or teach the students how to solve it mathematically.
