X^2 plus 2y divideed by 2x plus 3z equal

(x^2 plus 2y")

    2x(2x + 3)

Step-by-step explanation:

Doing this problem correctly requires the application of "order of operations" rules.  "x^2 plus 2y" actually means "(x^2 plus 2y"), and so your

x^2 plus 2y divided by 2x

comes out to:

(x^2 plus 2y")

         2x

If we now divide this result by "2x plus 3z," we get:

  (x^2 plus 2y")

            2x

      2x + 3

or:

(x^2 plus 2y")

    2x(2x + 3)

to determine the unit cost your would divide the total cost by the number sold.
