Understanding Factorization

The video tutorial explains the concept of factorizing, known as factoring in the US, which involves putting expressions into brackets. It covers the process of finding factors, which is a form of simplifying expressions. The tutorial provides examples of factorizing expressions like 12x and -8, and 6y^2 and 12y, by identifying the highest common factor. It emphasizes the importance of checking the factorized expression by expanding the brackets. The video concludes with practice exercises and hints at future topics like factorizing into two brackets and the difference of two squares.
