(3x^3-2x)-(6x^3+6x+8)

First arrange the polynomial, leaving gaps as required

3x^3  -2x

6x^3  +6x  +8

Then change the signs in the second part of the polynomial to ensure that the –ve sign outside the bracket is catered for.

3x^3  -2x

-6x^3  -6x  -8

-3x^3  -8x  -8

So the answer will be

-3x^3-8x-8
