Pre-Calculus - Applying foil to multiply complex numbers (3-2i) (4-7i)

The video tutorial introduces the box method as a clear and organized approach to multiplication, especially when dealing with binomials. The instructor explains how to set up the box method, calculate areas, and simplify results by combining like terms. The method is preferred over FOIL for its clarity and reduced error potential. The tutorial concludes with a final problem to reinforce the concepts learned.
