Simplifying Radicals with Factor Trees

The video tutorial introduces a new method for factoring, explaining the process in detail. It provides a step-by-step example of factoring numbers, demonstrating how to group and simplify radicals. The tutorial concludes with a summary of the key points covered.

What is the first step in simplifying radicals using the factoring method?

• Identify the largest number that can be factored out.

• Divide the radicand by the smallest prime number.

• Square the radicand.

• Take the square root of the radicand.
