Answer:

- 2a² - 5a + 4ab - 2b + b²

Step-by-step explanation:

Distributing the parenthesis gives

= - 2a² - 2ab + 10a - 15a + 6b + 6ab + b² - 8b ( collect like terms )

= - 2a² + (10a - 15a) + (- 2ab + 6ab) + (6b - 8b) + b²

= - 2a² - 5a + 4ab - 2b + b²

------------------------------------------------------

coefficient of the a² term is - 2

coefficient of the ab term is + 4

coefficient of the b term is - 2
