Answer 5

An extraneous solution is a solution which can be solved for but when substituted into the original equation, does not work. Basically, what that means is when you solve, that will be the answer but when you test the answer it will almost be as if it isn't the answer. I hope I gave you sufficient help, you were really vague so I wasn't sure what you meant. If you have a specific question, please post them here.
