In this section we will give the Binomial Theorem and illustrate how it can be used to quickly expand terms in the form (ab)^n when n is an integer In addition, when n is not an integer an extension to the Binomial Theorem can be used to give a power series representation of the termIf the seventh term from the beginning and end in the binomial expansion of (3 2 3 3 1 ) n are equal, find n View solution If the number of terms in the expansion of ( 1 2 x − 3 x 2 ) n is 36, then n equals4x 2 is (2x) 2, and 9 is (3) 2, so we have 4x 2 − 9 = (2x) 2 − (3) 2 And that can be produced by the difference of squares formula (ab)(a−b) = a 2 − b 2 Like this ("a" is 2x, and "b" is 3) (2x3)(2x−3) = (2x) 2 − (3) 2 = 4x 2 − 9 So the answer is that we can multiply (2x3) and (2x−3) to get 4x 2 − 9
