You did not tell what you want to learn, know, or understand.
You want to find if the last two expressions are factors of the degree-four polynomial expression?

One way is to try this:
Let x=-2.
Substitute into the polynomial. Result 0 or not?
Let x=-4.
Substitute into the polynomial. Result 0 or not?

---
Something is not right in the first expression (polynomial?). Missing exponentiation symbol?
--
Anyway, if you divide using either polynomial division or synthetic division successively for the two binomials, the result will give you ;
so you could say the given polynomial (degree four) is
