How to simplifying an expression when dividing complex numbers by multiplying by conjugate

The video tutorial explains the process of simplifying expressions involving imaginary numbers. It begins by discussing why multiplying by i is incorrect and introduces the concept of using the conjugate to eliminate i from the denominator. The tutorial then demonstrates applying the distorted property and FOIL method to simplify expressions. It further explains the importance of simplifying i squared to negative 1 and clarifies the division property when terms are separated by addition and subtraction. The video concludes with a recap of key points and final thoughts.
