The Conjugate Pair Theorem - Example 1
By PatrickJMT
The Conjugate Pair Theorem - Example 1. In this video, I show that if we know a complex root, we can use that to find another complex root using the conjugate pair theorem. Just a basic idea of the theorem.

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.
