A lot of these factoring problems require multiple steps, but not this one. This has a common factor, and that's about it. The common factor is 18x^2, so take out this common factor:
18x%5E3-36x%5E2
18x%5E2%28x-2%29+ The final answer is NOT given.

Now, look at the choices that ARE given. The C answer is a factored form of this problem, but it is NOT factored completely. It could be a trick question, or it could be a poorly stated problem. Ask your teacher for his/her opinion of this one. It might even be an oversight or an error by the one who made up the problem.

If you need more problems that work out better than this one did, please see my website under Basic Algebra, Chapter 2.
