Let’s expand our A Math horizon. Additional Mathematics Binomial Theorem Practice Questions with Answers for download. Here’s the next set of practice that we can work on. Welcome to question #13. IF you are preparing for the GCE O levels Add Math paper, this Binomial Theorem represent the essentials that you need to understand how Binomial Theorem works with expansion. Righty, so how do we need to train to get that A1? Ok first, get to know the basics. How do you use the general term (r+1)th of Binomial Theorem in Add Math? What is it? Where did the derivation come from? Next, know intimately Pascal’s Triangle. Finally, how to expand to get the exact term we want?

Now we get to this question. It is pretty straight forward. The first question is a prep for the follow through in the next question. Get the first answer right, make sure of it. Then substitute it into the second one. They give two sets of information. The first one is to get the value of k. Because you need this to use in the next part. The second set of information in this Add Math Question is to isolate the term that is a constant. So expand judiciously, making sure you only get the terms with no constant. Then its all the freeway home from there on. So what are you waiting for? Its easy peasy lemon squeezy… not that difficult to get that A1 in Add Math really.
