The product of two consecutive positive even integers is 440. what are the integers? show all work.

If the average of the two integers is x, the product of the two integers is
  (x-1)(x+1) = 440
  x² - 1 = 440
  x² = 441 = 21²

21 is the odd integer between the two even integers you seek.

The integers are 20 and 22.

No because if you do the higher number minus the lower number you will get a positive. if you do it the other way around you will get a negative number
