Here are the essential concepts you must grasp in order to answer the question correctly.
Radical Equations
Radical equations are equations that involve roots, such as square roots or fourth roots. To solve these equations, one typically isolates the radical expression and then raises both sides of the equation to the power that eliminates the root. This process may introduce extraneous solutions, so it's important to check all potential solutions in the original equation.

Isolating Variables
Isolating variables is a fundamental algebraic technique used to solve equations. It involves rearranging the equation to get the variable of interest on one side and all other terms on the opposite side. In the context of radical equations, this often means moving the radical expression to one side before applying operations to eliminate the root.

Extraneous Solutions
Extraneous solutions are solutions that emerge from the process of solving an equation but do not satisfy the original equation. This is particularly common in radical equations, where squaring both sides can introduce solutions that are not valid. Therefore, it is crucial to substitute any found solutions back into the original equation to verify their validity.
