The profit earned by selling a quantity of x + 2 of a product is given by the expression x4 − x3 − 24. what is the average profit per unit of product sold? a. x^3-3x^2+18 b. x^3-3x^2+6x-12 c. x^3-3x^2+6x- 12/x+2 d. x^3-3x^2-18 e. x^3-3x^2-18/x+2

(x^4-x^3-24 ) : (x+2)= x^3 -3x^2+6x-12

x^4 - x^3 - 24 | x+2 
-x^4 -2x^3          x^3 -3x^2+6x-12

/    -3x^3-24
     +3x^3+6x^2

         /     6x^2-24 
               -6x^2-12x

                / -12x-24
                    12x+24
                   
                       =   =          
The answer is B
