Solving Radical Equations Video 2
Solving equations with even roots and checking the solutions
Solving Radical Equations Video 4
Author: John Fisk
This video solves the following equations with multiple radicals and shows how we need to be careful about domain and range restrictions when the roots are even. You can try to solve the problems before watching the video and click "Reveal Answer" to see if you are correct.
Problem: Solve the following equations.
- \(7\sqrt{x}+3=5\sqrt{x}+11\)
- \(2\sqrt[3]{x+4}-\sqrt[3]{2x-1}=0\)
- \(x=16\)
- \(x=-\dfrac{11}{2}\)
