Answer:

12t² - 9t - 2

Step-by-step explanation:

Combine like terms. Like terms have same variable with same exponents.

(7t² - 6t-4) + (5t² - 3t+2) = 7t² - 6t-4 + 5t² - 3t+2

                                      = 7t² + 5t²   - 6t - 3t  - 4 + 2

                                       =  12t² - 9t - 2
