A Focus on Square Roots


Description

In the next two lessons, students work with radical expressions and equations. They extend their understanding of the idea that not all operations are invertible, which was explored in Algebra I and continued in the previous lessons on solving rational equations. Squaring both sides of an equation in some cases produces an extraneous solution. They also continue to work with rational expressions and equations as seen in the previous lessons, but those expressions now contain radicals.
