1. If n is very large, then it is very difficult to find the coefficients. 2. To find any binomial coefficient, we need the two coefficients just above it. To solve the above problems we can use combinations and factorial notation to help us expand binomial expressions. For larger indices, it is quicker than using the Pascal's Triangle.

ALEVEL MATHEMATICS (9709) BINOMIAL EXPANSION AND RATIONAL FUNCTIONS Cambridge IGCSE


The general binomial expansion applies for all real numbers, n ∈ℝ. Usually fractional and/or negative values of n are used. It is derived from ( a + b) n, with a = 1 and b = x. a = 1 is the main reason the expansion can be reduced so much. Unless n ∈ ℕ, the expansion is infinitely long. It is only valid for |x| < 1.
