A note on the way questions are asked:
As you know, when asked to "solve" for x, you can plug the answers into the problem to see if you get a true statement.  To avoid plugging in to find a correct choice on a multiple choice test (to force you to actually solve the problem algebraically), we sometimes ask you to "find the sum of the solutions" or "find the product of the solutions" or simply "how many solutions".  To test whether you can complete the square, we could ask you to"find an equivalent equation."  This means start the process of solving by completing the square and note what each step looks like.  When you correctly get to a particular step you should find that equation as one of the choices.  On word problems, instead of having you find a solution, we could ask you to just set up a problem that would give the correct solution.  We tell you this now so that you are not caught off-guard on the exam.
