- expand a binomial expression of the form using Pascal’s triangle to find the coefficients of the terms.
Prerequisites
Students should already be familiar with
- forming Pascal’s triangle.
Exclusions
Students will not cover
- combinations or factorial notation,
- the general formula for a term in a binomial expansion.
