Is x³ + 2x² + 3x + 1 reducible over Q? If not, why not?

What is an irreducible / primitive polynomial?

What does irreducible mean, what is a prime element? Can you give an example for a primitive that is not irreducible or vice versa?

What can you say about the ring R [x]?

Which qualities of rings do you know, can they somehow be ordered (main ideal ring, ZPE, Euclidean)? What do the associated polynomial rings look like?

How can I construct a body for a polynomial P over a field K, which decomposes P into linear factors?

Q7) Factorise the polynomial f(x) = x3 − 2x2 + 2x − 1 into irreducible polynomials in Z5[x], i.e. represent f(x) as a product of irreducible polynomials in Z5[x]. Demonstrate that the polynomials you obtained are irreducible. I think i manged to factorise this polynomial. I found a factor to be 1 so i divided the polynomial by (x-1) as its a linear factor. So i get the form (x3 − 2x2 + 2x − 1) = (x2-x+1)*(x-1) which is...
