Algebra 2 - Math tutorial for simplifying a radical using the imaginary number i, sqrt(-144)

The video tutorial explains how to handle square roots of negative numbers by using properties of radicals. It begins with an introduction to negative numbers and square roots, then moves on to explain the properties of radicals. The tutorial demonstrates how to separate and solve radicals by breaking them into products, and finally, it covers calculating square roots of both positive and negative numbers, including the concept of imaginary numbers.

Explain why you cannot take the square root of a negative number directly.

What properties of radicals allow you to take the square root of products separately?

How can you separate -144 into two factors for taking the square root?
