How to determine if solutions are extraneous for absolute value equations

The video tutorial explains extraneous solutions in the context of absolute value equations. It begins by defining extraneous solutions and the concept of absolute value, using a number line for illustration. The tutorial then demonstrates solving absolute value equations, highlighting the possibility of having two cases. Finally, it shows how to test solutions to determine if they are extraneous by plugging them back into the original equation.

What is an extraneous solution in the context of absolute value equations?

Describe the process of creating cases when solving absolute value equations.

Explain how to determine if a solution is extraneous after solving an absolute value equation.

What steps should be taken to verify if the solutions obtained from an absolute value equation are valid?

How can you identify if a solution is not part of the original equation after substitution?
