GCSE Secondary Maths Age 13-17 - Algebra: Algebra - Explained

The video tutorial covers algebra questions focusing on expanding and factorizing expressions. Part A explains how to expand brackets by multiplying terms, while Part B delves into factorization, emphasizing the importance of identifying and extracting common factors. The tutorial also discusses the marking scheme, highlighting the criteria for full and partial marks based on the completeness of factorization.
