simple-equations-that-require-taking-a-square-root-grades-78-or-pre-algebra

I show how to solve simple equations such as x^2 - 4 = 21 where the solution process involves taking a square root. These types of equations arise naturally from using the Pythagorean Theorem, and thus this lesson prepares students for that. The lesson suits best grade 7 or 8 math (pre-algebra).
