Tutorial - Dividing complex numbers ex 22, (4 - 3i)/(-1 - 4i)

The video tutorial explains how to divide complex numbers by using the conjugate method. It begins with an introduction to the concept of conjugates and their role in simplifying complex fractions. The instructor demonstrates how to multiply binomials using both the FOIL and box methods. The tutorial then focuses on simplifying the numerator and calculating the denominator of the complex fraction. Finally, the results are combined to form the final complex number in the form of a + bi. The video concludes with a summary of the steps involved in dividing complex numbers.
