Not if you're asking to be praised.  The best praise is that which comes your way without your asking for it.

Ms-B:  If you felt really stuck, you could multiply out the supposed factors in each case and see whether your results are the same as the original expression.  That shouldn't take long.

Alright a bunch of you are saying correct, and some are saying incorrect. >.> Which is it so I can move on? or redo the problem!

mathmale · Answer

Ms-Brains:  I suggested earlier that you multiply out the 3 sets of binomial factors and then compare your results to a^2-8a-16.  I still think that that'd be the easiest and fastest approach to finding the correct answer to this problem.
