Answer:

your answer is given below

Step-by-step explanation:

2ab-2b^2+7a^2+7ab=7a^2-2b^2+9ab

Answer 2

Answer:

7a² + 9ab - 2b²

(a + 1)(7a - 2) - 4ab

Step-by-step explanation:

2b(a-b) + 7a(a+b)

2ab - 2b² + 7a² + 7ab

7a² + 9ab - 2b²

7a² + 9ab - 2b² - 4ab + 4ab

7a² + 5ab - 2b² - 4ab

((7a + 7)(7a - 2))/7  -  4ab

7(a + 1)(7a - 2)/7 - 4ab

(a + 1)(7a - 2) - 4ab
