1. Pascals Triangle and the Binomial Expansion

2. Pascal’s Triangle
Pascal was not the first to discover the triangle however he was the first to bring it to Europe and prove it.
The Chinese knew about the triangle since the 13 century

3. Pascal’s Triangle: Write it on one side of your triangle

4. Binomial Expansion Using the distributive property many times
Example: (x +2)³
=(x +2) (x +2) (x+2)
=(x+2) (x² +4x +4)
=x³ +6x² +12x +8
Any easier way is to have the binomial expansion follow Pascal’s triangle

5. Write the binomial expansion on the other side of the triangle
