Find the third term in a binomial expansion to the 7th power

The video tutorial explains the process of binomial expansion, focusing on finding the third term. It begins by rewriting the expression and identifying the first three terms. The teacher then uses Pascal's Triangle to determine the coefficients needed for the expansion. Finally, the third term is simplified, resulting in a final expression. The tutorial emphasizes understanding the pattern and process of binomial expansion, particularly the role of coefficients and the use of Pascal's Triangle.
