GCSE Maths - What is Difference of Two Squares (DOTS) #39

The video tutorial introduces the difference of two squares technique for factorizing expressions. It explains that this method applies to expressions of the form A^2 - B^2 and demonstrates how to factorize them into (A + B)(A - B). The tutorial provides several examples, including X^2 - 25, 49 - P^2, 16X^2 - 9Y^2, 36 - 4X^2, and P^2 - 25Q^2, showing step-by-step how to identify the squared terms and apply the technique. The video concludes by verifying the factorization through expansion, ensuring the method's correctness.
