To answer your first question, you need to review polynomial long division. You will be left with a remainder.

I got the answer to be

3q^2 +6q +12 + [30/(q-2)]

The term in brackets is the remainder

For your second question, the answer will be the volume divided by the area of the side that you know, or

(2x^3 +x -2)/(2x^2 +3x -3)

This also results in a remainder term. The denominator is not a monomial factor of the numerator.

The assigned you a pair of rather messy problems.
