Answer:

The answer to your question is a² + 9a + 20

Step-by-step explanation:

10a² + 3a + 25 - (9a² - 6a + 5)

- Remove parentheses changing the sign of the second polynomial

10a² + 3a + 25 - 9a² + 6a - 5

- Group like terms

(10a² - 9a²) + (3a + 6a) + (25 - 5)

- Simplify and result

a² + 9a + 20
