Simplifying Surds in the Context of Expanding Brackets

The video tutorial explains how to simplify surds, especially when expanding brackets that include square roots. It covers three key rules for simplifying surds and demonstrates their application through examples. The first example involves expanding and simplifying a single bracket, while the second example uses the FOIL method to expand and simplify double brackets. The tutorial emphasizes the importance of careful expansion and simplification using surd rules and encourages practice to master the topic.
