    You don't know is WHAT is right? Do you mean you already have an answer that you want to check? Why not just multiply the factors you have together and see if you get the correct thing?

    If you happen to multiply the factors and not get the same thing, then here's a hint: notice that t^2 + 4t + 4 is a perfect square (t+2)^2
