Intro to Conjugates

​Dividng Complex Numbers is similar to Dividing Radicals.

​

​When Dividing Radicals, you must get rid of any radicals in the Denominator.

​

​When Dividing Complex Numbers, you must get rid of any imaginary numbers in the Denominator.

​

​To do this, you must multiply by the Conjugate.

​

​

​The conjugate of a complex number in the form of a + bi, is a - bi

​

​The conjugate of a complex number in the form of a - bi, is a + bi

​When Dividing Complex Numbers: Multiply the numerator and denominator by the conjugate of the denominator and simplify.

* Sometimes it is only necessary to multiply by "i" to get rid of the imaginary unit - if the denominator only has one term.

​

​Remember that i² = -1.
