I have removed all annotations from my videos that were used to correct errors (YouTube is
getting rid of Annotattions) Any errors in the videos have been corrected in the NOTES.

We call radical Equation, any equation that involves square roots. These equations are solved
by raising both the left hand side and the right hand side to the square to eliminate the roots.
If not all the square roots were eliminated, we repeat the process. By doing this, we may be
introducing "extraneous" solutions (fake solutions). So, after finding the solution(s) we need
to plug them into the original equation to see if it is verified.
