Naturally you need to understand numbers if you want to pass your IGCSE GCSE maths exam. But we use different types of numbers in all sorts of situations. Follow this selection of links to more of my pages where I explain to you step in step the maths topics.
What is Factoring
In my previous videos you have learned how to expand expressions and get rid of those brackets. On past IGCSE GCSE maths exam questions you will also be asked to factorise expressions. In the next videos you will understand what is meant with factorising algebraic expressions. Many students do not understand factoring and have problems with it. However, if you look at the entire playlist from start to end, you will understand factoring and significantly develop your understanding of algebra. Factoring expressions is crucial for every maths student to understand if they want to pass their maths exams. In the first video I will explain in general what factoring is. Then I will explain the following methods to factorise an expression:
- How to factorise by taking out the Highest Common Factor
- How to factorise by grouping
- How to factorise using the Inspection Method
- How to factorise the difference of two squares
You need to understand all types of factoring if you want to pass your maths exam. So sit back and relax and make sure to try all the maths examples questions yourself first before looking at my solution and answers. If you still don't understand Factoring, ask me your question on the forum on the homepage of this site and I will help you with your maths. Good luck and have fun!
What is Factorising Algebraic Expressions by using the Inspection Method
In the following videos I will explain to you how to factorise algebraic expressions using the inspection method. I will teach you step by step what to do and which questions you should be asking yourself. So study the following example questions during your maths revision and prepare yourself to pass your IGCSE GCSE Maths exam!
You now understand how to factorise using the inspection method. But how can you use the inspection method if the coefficient of the squared term (x squared) is not 1? In the following videos I will explain to you by giving you many example maths questions how to use the inspection method when the coefficient of the x^2 term is not 1. Let me know if you still don't understand factoring. I will be glad to help you with your maths and answer your questions. Try yourself first. Good luck and have fun!!
What is Factorising by finding the Difference of two Squares
The last type of factoring you need to understand to pass your IGCSE GCSE Maths exam is the difference of two squares. Many times this type of question appears on a maths exam. I will explain the difference of two squares in the following two videos. I will give you many example questions which you can try to find out whether you understand how to factorise the difference of two squares.
Congratulations!! You now understand all types of how to factorise algebraic expressions! Do not stop with your maths revision now but learn how to evaluate expressions by substitution. Follow the link and I will explain all you need to know about evaluating expressions by substitution. See you there!
