(2n^2-5n-6)+(-n^2-3n+11)

The answer to your question is  n² - 8n + 5

Step-by-step explanation:

Data

               (2n² - 5n - 6) + (-n² - 3n + 11)

- Remove the parentheses, the signs of the terms of the second parentheses do not change.

               2n² - 5n - 6 - n² - 3n + 11

- Group like terms

               (2n² - n²) + (-5n - 3n) + (-6 + 11)

- Simplify

                  n² - 8n + 5
