MATHS - Algebra - Expanding Square Brackets

This video tutorial explains how to expand square brackets by treating them as double brackets. It reviews the process of expanding double brackets, where each term in the first bracket is multiplied by each term in the second bracket. The video provides an example of expanding squared brackets and simplifies the expression to x squared minus 10x plus 25. Viewers are encouraged to practice with provided problems and are reminded to ensure the final expression has exactly three terms. The tutorial concludes with a recap of the key steps involved in the process.
