Solving Radical Equations Concepts

The video tutorial covers solving a complex radical equation with radicals on both sides. The instructor demonstrates isolating the radicals, squaring both sides of the equation twice, and simplifying to find potential solutions. After solving, the instructor checks the solutions to determine their validity, concluding that the equation has no valid solutions. The lesson ends with instructions for classwork and homework assignments.

What is the first step in solving an equation with radicals on both sides?

• Add a constant to both sides

• Isolate one of the radicals

• Subtract a constant from both sides
