Last lesson, I recapped with my students the essence of Binomial Theorem in A-Math and upon searching my website, I found that I have written quite a number of posts on this topic.

I'm going to list down the points you need to know before you go for your exams.

Do you know

- How to use the Binomial formula provided on the formula sheet? (term by term expansion, (r+1)th general term, factorial formula)
- What's term independent of
*x*? - Which term to use in a double bracket expansion?
- How to apply Binomial concepts in evaluating values?

Binomial theorem is closely linked to Indices and every year, there is always one question worth 5 - 7 marks in 'O' Levels.

Hope you find this post beneficial and I would love to hear your comments on Binomial theorem. Do you like this topic or you don't? Leave me a comment.
