    A quick recap of simplifying and combining radicals. A good review if you have already learned about square roots and would like to see a few example problems. Also, a good recap of conjugates. Watch only if you understand multiplying binomials (FOIL).

    I learned this as the basics. It helped me recap on what I had lost over the summer.

    Not bad, but more voice or explanation would improve this video. I can see how I could effectively use in my classroom.
