Tutorial - How do we multiply complex numbers ex 12, (-1 - 5i)(-1 + 5i)

The video tutorial explains special factoring techniques, focusing on the difference of two squares. It begins by identifying the difference of squares and its formula, a^2 - b^2 = (a - b)(a + b). The instructor demonstrates how to apply this formula to complex numbers, specifically using the example of -1 and -5i. The process involves squaring the terms and simplifying the expression to reach the final result. The tutorial concludes with a summary of how to multiply complex numbers using the difference of squares method.
