Factoring using the difference of two squares with multiple variables

The video tutorial explains the concept of the difference of squares, a method used in algebra to factor expressions. The teacher introduces the definition, which involves recognizing expressions of the form a^2 - b^2 and factoring them into (a + b)(a - b). The tutorial demonstrates how to identify square numbers and apply this method to a specific problem, showing step-by-step how to rewrite terms as squares and factor them. The video concludes with the final factoring form, emphasizing the simplicity and effectiveness of the method.
