Tutorial - Combining complex numbers ex 8, (8 + 20i) - (8 + 12i)

The video tutorial explains how to apply the distributive property, especially when dealing with negative signs outside parentheses. It demonstrates the process of distributing the negative sign across terms within the parentheses. The tutorial then transitions to combining complex numbers by focusing on combining real and imaginary parts separately. The final result of the example provided is a complex number with only an imaginary part.
