Algebra 2 - Dividing complex numbers by multiplying by i, (8-6i) / 3i

The video tutorial introduces the concept of imaginary numbers, focusing on the imaginary unit 'i', which is defined as the square root of -1. It explores the challenges of dividing complex numbers and explains that instead of direct division, expressions are simplified using multiplication by 'i/i'. The tutorial also covers the standard form of complex numbers, a+bi, and demonstrates how to express results in this form.

Describe the process of multiplying by 'i/i' to simplify a complex fraction.
