Solving by difference of two squares when not a square number

The video tutorial demonstrates how to factor an expression using the difference of two squares technique. It begins by explaining the concept and setting up the equation to be factored. The instructor then applies the difference of squares method, identifying the terms a^2 and b^2, and solving for the variables by taking square roots. The tutorial concludes by summarizing the solution and emphasizing the applicability of the technique even when dealing with non-square numbers.
