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.

Hi, I'm Ai Ling Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths. I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way. I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
