This week in math lesson 8.1 we learn how to solving absolute value equation algebraically. when solving with an absolute value of a square root you may come across extraneous solution which are solution that are not true solution  of the equation given algebraically we can find out whether a solution is extraneous by verifying and inserting the “x” value beck into the original equation to see if the equation is true or to see whether both sides equal each other.
