Solving Quadratics with Square Roots Practice Set
By Zainab A.
A practice set for 9th graders that teaches the square root property, walking students step by step through isolating the squared term, taking square roots, and handling the plus-minus solutions for equations of the form ax² = c. It builds algebraic reasoning and fluency with radicals, with worked models and reasoning notes at each step to support independent practice.
Customize for your classroom
Teacher Guide & Tips
- Use this as guided practice after a brief introduction to square roots, working through the step-by-step model together before students attempt the problems on their own in about 30 to 40 minutes.
- Discussion question: Why does x² = 9 have two solutions, and what would change if the equation were x² = -9?
- Scaffold for struggling readers: Have them rewrite each step in their own words in the Action & Reasoning column and check their answers by substituting back into the original equation.
- Extension for advanced students: Ask them to explore equations where the coefficient is negative or where the radical does not simplify, and to explain when solutions are irrational.
- Estimated time: Roughly 40 to 50 minutes including the worked model, practice problems, and a short debrief.
