Question 830745: Extraneous solutions are solutions that cannot be found?
Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! No, extraneous solutions can be found they just do not solve your original equation which is why you should always check any answer you obtain with your original equation. This is critical with problems involving radicals, logarithms, polynomial expressions in a denominator, etc. but good practice to do with every type of problem.
