Answer 1

Answer:

5$a^{2}$+ab+6$a^{2} b$

Step-by-step explanation:

2a(a-b)=2$a^{2}$-2ab

-3a(b-a)=-3ab+3$a^{2}$

6ab(a+1)=6$a^{2} b$+6ab

5$a^{2}$+ab+6$a^{2} b$

Answer 2

Step-by-step explanation:

5a^{2}a

2

+ab+6a^{2} ba

2

b

Step-by-step explanation:

2a(a-b)=2a^{2}a

2

-2ab

-3a(b-a)=-3ab+3a^{2}a

2

6ab(a+1)=6a^{2} ba

2

b +6ab

5a^{2}a

2

+ab+6a^{2} ba
