Curated OER
Radical Equations
This task gives geometry learners practice in solving radical equations in one variable and zeros in extraneous solutions.
Curated OER
Extraneous Solutions
Students find the roots of quadratic equations. In this algebra lesson plan, students solve radical equations and identify the positive and negative roots. They graph and analyze their functions.
