Pearson A level Maths, Pure Year 2 Textbook (4.1)

In this video I explain what finite/infinite/valid/invalid expansions are. Then I go over how to expand a binomial using the binomial expansion formula; as well as covering the concept of finding the range of values of x for which an expansion becomes valid/finite.

Take care here, I believe your definition of valid/invalid is incorrect, and also |b| is not equal to b.
