An Example of Finding a Complex Conjugate
By Khan Academy
This video shows us how to find the complex conjugate of a complex number, then shows us one of the most useful uses of the complex conjugate. If you ever multiply two complex conjugates, you will get a real number as a result. This is very useful when we start dividing complex numbers!
Dividing complex numbers | Imaginary and complex numbers | Precalculus | Khan Academy
By Khan Academy
Here we see a guided example of how to divide two complex numbers. Remember to use the complex conjugate of the denominator. The whole point is to make the denominator into a real number, so if that doesn't happen, go back and check over your work very carefully.

This lesson covers complex numbers. Students learn that a complex number is the sum or difference of a real number and an imaginary number and can be written in a + bi form. For example, 1 + 2i and -- 5 - i root 7 are complex numbers. Students then learn to add, subtract, multiply, and divide complex numbers that do not contain radicals, such as (5 + 3i) / (6 - 2i). To divide (5 + 3i) / (6 - 2i), the first step is to multiply both the numerator and denominator of the fraction by the conjugate of the denominator, which is (6 + 2i), then FOIL in both the numerator and denominator, and combine like terms.
