In this lesson on Radical Polynomial Expressions (Part 2), you will learn how to find solutions for radicals of polynomial expressions. Through the use of prime factorization, division and multiplication of powers, and understanding basic root definitions, you will be able to simplify complex radical expressions with ease. While a calculator may be helpful in some instances, it is important to try and work through the problems without one as it will be faster in cases where decimals are not preferred.
