Hello, I'm in Business with Algebra and Calculus and I know the Calculus pretty well but it's this particular type of distributing that I'm having trouble with. For instance..

(x^4-2) * 3(x^2+2)^2 *2x + (x^2+2)^3 * 4x^3

There is just so many numbers I can't figure out which numbers and values I should take out

The answer to it is:

2x(x^2+2)^2[3x^4 - 6 + 2x^4 + 4x^2]

Then:

2x(x^2 +2)^2 * (5x^4 + 4x^2 - 6)

I just need to figure out how to do this then I think I will be good for my exam.
