This video tutorial covers the process of factoring special case polynomials using the CUDA software. It begins with an introduction to the concept of factoring, followed by detailed examples of factoring expressions like a squared minus b squared and a squared minus 2ab plus b squared. Each example is broken down step-by-step, demonstrating how to find the square roots and apply them to the factoring formulas. The video concludes with a reminder to use subscripts to avoid confusion and encourages viewers to practice the methods shown.
