Can I make this general statement?

$$A^{n}(B+C)^{n} = (AB+AC)^{n}$$

?

You're comfortable that (ab)^n = (a^n)(b^n) (aside from a few restrictions) correct? Is there anything you can do to change your expression into the form (a^n)(b^n)?

If those are matrices, do you think you might need that A and B+C commute to make that rearrangement?

not matrices but polynomials...

They commute. So you should be fine.
