Square Roots and Radicals 14
In Square Roots and Radicals 14, students learn how to multiply square roots using the distributive property and two binomials using the FOIL method. The video covers various techniques for factoring and simplifying expressions with square roots, including squaring binomials containing square roots. Students will also learn how to recognize the difference between multiplying and squaring binomials with square roots, which will prepare them for future lessons on dividing with radicals.
Square Roots and Radicals Part 14 covers multiplying with square roots using the distributive property and multiplying two binomials using the FOIL method. Includes squaring binomials containing square roots.

Staff Review
This lesson picks up where the previous lesson left off. You will get more practice with example problems of multiplying and distributing radical expressions in this lesson. The numbers are a bit larger this time and problems are a bit more difficult in general, but the methods are the same. This is a very good tutorial for those who need more practice. Also, some special cases of multiplying binomials with radical expressions are shown.
