Binomial expansion for positive integer powers

By the end you’ll be able to

• Expand $(a+b)^n$ for positive integer values of $n$ using the binomial theorem.
• Use and interpret binomial coefficients, including notation such as $\binom{n}{r}$ where used by the course route.
• Find the general or specific term in a binomial expansion.
• Determine a required coefficient or unknown constant from a binomial expansion.
