PASCAL'S TRIANGLE The triangle on the previous page is known as Pascal's Triangle. French mathematician Blaise Pascal developed a triangular pattern to describe the coefficients for the expansion of a

binomial (a + b)", for consecutive values of "n" rows. a) Based on the expanded form for binomials on the previous page,describe what happens to the exponent of the variable "a" in each of the binomial expansions. b) Similarly, describe what happens to the exponent of the variable "b"in each of the binomial expansions.
