Multiplying Radicals of the Same Root - Problem 3 224 views
We wish to multiply binomials that have roots, or radicals, in one or more terms. We can approach this in the same way we would a polynomial product, where we often use FOIL to multiply the first terms, outside terms, inside terms, and then last terms. From there, we'll combine the radicals that have the same radicand, and combine the integers. If you're careful with parentheses, you can check your answer on a calculator with decimal approximations.
