Oh my, there's a variable inside the radical. How will you ever solve this one? The teacher explains step-by-step just how to solve this radical equation. She also shows how to check to make sure the answer is the correct one.
This practice worksheet includes simple radical equations, and some quadratic equations that can be solved by the square root method. There is good practice here in checking the solutions, and a few graphing problems.
Eleventh graders investigate radical functions. In this Algebra II activity, 11th graders use TI-Navigator and Navpad to explore the effect of changes in parameters on the graphs of radical functions.
Students observe and solve examples of equations involving radicals. They complete a Doing Battle With Radical Equations worksheet and checklist.
Students explore extraneous roots to radical equations. In this Algebra II lesson, students solve equations which are typically "unanswerable" with paper and pencil. The use of the TI-npire provides a method of solution and moves the focus of the lesson to flexibility in problem solving.
Students explore radical equations. In this Algebra II lesson, students solve radical equation graphically. Students examine the roots of quadratic and cubic equations. TI-nspire handheld and appropriate application necessary.
Continue your lecture on radical equations with this video, which features Sal solving a few more problems with his classic clarity and understandable way. Young mathematicians will benefit immensely from seeing his cool hand guide the increasingly difficult equations.
In this radical equations worksheet, students solve given radical equations. They solve problems containing variables, exponents, and fractions. This two-page worksheet contains 20 multi-step problems.
In this algebra worksheet, high schoolers match radical equations that are solve by squaring both sides. Once they finishing matching equations, they decode the hidden message. There are 13 questions.
Bringing it all together in this video, Sal incorporates the concepts from previous lectures (quadratic formula, multiplying polynomial expressions, radical expressions, exponents). This video would be a great way to end a unit or review for a unit test in your algebra class.
