The binomial theorem. Pascal’s Triangle. What you’ll learn To expand a binomial using Pascal’s Triangle. To use the binomial theorem. Vocabulary Expand, Pascal’s triangle, binomial theorem.
Essential understanding: Expand using the distributive property. Row Power Expand form Coefficients only
And this is Pascal’s triangle: this is a triangular array of number in which the first and last number of each row is 1. Example 1: Using the Pascal’s triangle. What is the expansion of ? The exponents for a begin with 6 and decrease to 0 The exponents for b begin with o and increase to 6
Binomial theorem: For every positive integer n, Your turn: What is the expansion of (a + b)^8? Answer
Your turn again What is the expansion of (3x – 2)^5? Use the binomial theorem. Think
