Algebra 2 - Where do imaginary numbers come from

The video tutorial introduces imaginary numbers, starting with a review of solving equations using inverse operations and factoring techniques. It explains how to find roots of equations and discusses real numbers. The tutorial then introduces the concept of imaginary numbers, focusing on the imaginary unit 'i', which represents the square root of negative one. The video explains why the square root of a negative number is not possible in the real number system and how 'i' is used to represent such cases.
