Simplifying Products of Square Roots Using Complex Numbers

The video tutorial explains how to simplify the product of square roots using complex numbers. It begins by introducing the concept of simplifying square roots and the role of complex numbers, specifically the imaginary unit 'i'. The tutorial then breaks down negative square roots into products involving negative one. It proceeds to simplify the product of these square roots step-by-step, ultimately leading to a final calculation that results in negative six.
