You are asked, when you submit a question, to show any work you have done to try to solve the problem. That way, we can help you see what you did wrong. That is a lot more helpful to you than just having us show you how to do the problem.

I'll set up the problem for you; you can finish solving it and compare it to the work you did earlier to try to see your error....
