Solving Radical Equations and Fractions

The video tutorial explains how to solve a radical equation by isolating the radical, simplifying the equation, solving for x, and rounding the solution to four decimal places. It also includes verifying the solution by substituting it back into the original equation to ensure accuracy.

What is the first step in solving a radical equation with one radical?

• Add a constant to both sides

• Isolate the radical on one side

• Square both sides immediately

• Multiply both sides by a constant
