    If you want an answer to your question, you might consider taking a few seconds to actually reread what you posted. Then you might notice that simply copying and pasting doesn't work well for math problems on this site. The + and - signs tend to get dropped.

    Try retyping the problem manually, and then we'll be able to help you.
