Let y = x1/3. Then, I assume you can see that you can write the expression you were given as
y2 - 7y + 12 = 0 (*)
This is a trinomial that you should easily be successful in factoring . If you don't, then there is no point in writing down the full solution.
Once, you are done factoring (*), replace y with the original x1/3 ... Et voila'. ....

So, if you did, you ended up with
(y-3)(y-4)
and upon substituting back y=x1/3,
(x1/3-3)(x1/3-4)
which is the factorization you were asked to provide.
