2x cubed + x -2. the height of the prism is 2x-1, and the length of the prism is x+2. find the width of the prism.

    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.
