Factoring.

The answer is supposed to look like this.

EXAMPLE:

5x(6x+2)(6x-2)

Step-by-step explanation:

2y×(5-4y)×(5+4y) here you go now please help me if you can

Since each bottle is made up of 2-liter of the active solution, in order to determine the number of doses of the medication that can be made, we just have to divide 2 L by 4x10^-3.
                  number of doses = (2 L) / (4x10^-3L/dose) = 500 doses
Therefore, the pharmacy can make 500 doses of the medication.
