  4. 4. Ex: Solve. Don’t forget to check your solutions!!
  5. 5. Ex: Solve. Don’t forget to check your solutions!!
  6. 6. Ex: Solve. Factor this to solve! Don’t forget to check your solutions!! Only use the positive answers when checking solutions. Solution
  7. 7. So, why didn’t one of the solutions work? <ul><li>The solution that did not work is called an extraneous solution . </li></ul><ul><li>An extraneous solution is a false solution. </li></ul><ul><li>This is the reason why you MUST check all solutions!! </li></ul>
