Ex: Expand the following binomial:
n = 4, so use the 5th rowin Pascal’s triangle
The first variable “a” will bedescending in power, starting with 4
The second variable “b” will beascending in power, starting with 0
n = 5, so use the 6th rowin Pascal’s triangle
The first variable “a” will bedescending in power, starting with 4
The second variable “b” will beascending in power, starting with 0
