Answer:

-m² + 13m + 11

Explanation:

To simplify the expression, we must combine the like terms. So

(8m + 5m² + 7) - (6m² - 5m* - 4)

The - means that every term inside of the second () will change signs. So, we have

8m + 5m² + 7 - 6m² + 5m + 4

Now we combine the like terms.

With m²: 5 - 6 = -1

With m: 8 + 5 = 13

Independent: 7 + 4 = 11

The simplified expression is:

-m² + 13m + 11
