Answer 1

Answer:

After solving this equation becomes:

7+ 10a +10b - 8a²- 8b² -16ab

Step-by-step explanation:

7+10 (a +b) - 8(a +b)²

7 + 10a +10b - 8(a² + b² +2ab)

7+ 10a +10b - 8a²- 8b² -16ab

Answer 2

Answer:

Step by step explanation:

-8(a+b)^2+10(a+b)+7

=-8(a^2+b^2+2ab)+10a+10b+7

=-8a^2-8b^2-16ab+10a+10b+7
