Answer 3

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)

Answer 4

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

Answer 5

oh ok i'll use synthetic division

Answer 6

to find the average profit per unit sold we do (x^4-x^3-24)/(x+2)
