I think you are going to find that is irreducible in Q and therefore in Z.

What do you get if you multiply out the brackets and simplfy?

How about this one? What are the factors of:
3x(x+2y) + 4y(3x+2y)

Hi;
Or take it over to Wolfram.

hi deiv
Welcome to the forum.
You can simplify the problem by making the substitution
Then it becomes
I notice that x = -1 makes this expression zero, so by the factor theorem (x + 1) is a factor.
From there you can easily get the quadratic that goes with this and you'll find the formula will give another two factors.
Then you can go back to the m expression from there.

Pls factor completely: (m^9)-(3•m^3)-2
tnx....
