Answer:
1.Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation. In this video, we explain how and why we get extraneous solutions, by understanding the logic behind the process of solving equations.
2.When solving a radical equation, it is important to always check your answer by substituting the value back into the original equation. If you get a true statement, then that value is a solution; if you get a false statement, then that value is not a solution.
3.Follow the following four steps to solve radical equations.
Isolate the radical expression.
Square both sides of the equation: If x = y then x2 = y2.
Once the radical is removed, solve for the unknown.
