Factor using Rational Root Theorem.
This means our possible roots are
positve or negative (1,2,3,6). If we try positve 1, it is indeed a root.
This means that

is a root.
We can divide the top equation by the root (x-1). Our new equation is

Now we can factor this completely

So this equation in factored form is
