    so we have the profit=x^4-x^3-24 and the selling quantity=x+2 to find the average product per unit sold we do (x^4-x^3-24)/(x+2)

    in other words we want to divide x^4-x^3-24 by x+2 you can do this by long division or synthetic division

    to find the average profit per unit sold we do (x^4-x^3-24)/(x+2) * (correcting a word I put earlier)
