I tried using synthetic division but the graphs of the two were no where close

(x-3) should be a root. Go from there.
What does synthetic division have to do with graphs? Factor: . Did you notice that ? . . This means is a factor of
Note that . . Hence: is a factor of
Finally, we see that can be factored.
well i assumed that the factored form should have the same graph as the original equation but i didnt get the same graph. I have one question, what did you do to get (x+1)(x^3 - x^2 - 5x - 3)?
Since you know one root, you can use synthetic division on the polynomial. Also, you know that the only rational solutions are 1, -1, 3, -3, so you can look at those first, and see which of those are roots.
