Factor further? Expand?
Expanding this out using FOIL:
First:
3x^4 * 2x^3 = 6x^7
Outer:
3x^4 * 6 = 18x^4
Inner:
2 * 2x^3 = 4x^3
Last:
2 * 6 = 12
Adding all the terms up:
6x^7 + 18x^4 + 4x^3 + 12
There's the expanded form.

(3x^4 + 2)(2x^3 + 6)
= 6x^7 + 18x^4 + 4x^3 + 12
---------
Ideas: Expand it from the highest degree to the lowest.
