Final answer:
The coefficient of a term in a binomial expansion can be found using the binomial theorem and the combination formula.
Step-by-step explanation:
The coefficient of a term in a binomial expansion can be found using the binomial theorem. The binomial theorem states that for a binomial expression (a + b)n, the coefficients of each term can be found using the formula:
C(n, k) * a(n-k) * bk
Where C(n, k) is the combination formula, which calculates the number of ways to choose k objects from a set of n objects. It can be calculated using the formula:
C(n, k) = n! / (k! * (n-k)!)
