2mn(n - 4) - n²(2m + 8)

2mn² - 8mn - (2mn² + 8n²)

2mn² - 8mn - 2mn² - 8n²

8mn - 8n²

8n(m - n)

- - - - - - -s-

Here is the solution:

2mn(n-4)-n²(2m+8)= 2mn²-8mn-2mn²-8n²

=-8mn-8n²=-8n(m+n)

2mn(n - 4) - n²(2m + 8)

= 2mn² - 8mn - 2mn² - 8n²

= -8mn - 8n²

= -8n(m + n)

2mn(n-4)-n²(2m+8)

2mn^2-8mn-2mn^2-8n^2

-8mn-8n^2

-8n(m+n)

Math sucks, and I finished taking it in college so I'm DONE! I never have to do math again so ha ha ha!
