Teaching guide, sample answers and curriculum references
Before you begin
Factor quadratics, solve linear equations and interpret principal square roots.
How to use this worksheet
- Begin with: What restriction follows because the square root must equal a nonnegative right side?
- Connect the response to: List all roots of that quadratic.
- Ask students to apply the idea: Explain why squaring made x = 0 appear as a candidate although it fails the original equation.
A common mistake to discuss
An algebraic candidate is not a solution until it satisfies the original domain and equation.
