I am really stumped
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

You are just doing the problem backwards. In the first place, since there are two solutions, you know that you must have a second degree equation. If you were solving a quadratic, something that looks like:

You would factor the trinomial and have something that looks like:

Then you would use the Zero Product Rule to say:

so

or

so

Therefore, start at the end:

so

Likewise:

Now we have our two factors:

So all you have to do is multiply the binomials using FOIL and you are done.
