Jawaban:

2. -8a+7b+3a-b+3 = -8a+3a+7b-b+3 = -5a+6b+3.

3. 4a+5b-(2a-3b) = 8a²-12ab-10ab-15b = 8a²-22ab-15b.

4. -7a-8b+(5a+7b) = -35a²+49ab-40ab-56b = -35a²+9ab-56b.

5. -2a²+3a-4b-a²+2a+4b = -2a²-a²+3a+2a-4b+4b = -3a²+5a.

6. 5a²+11b²-3a-3a²-8b²+2b = 5a²-3a²+11b²-8b²-3a+2b = 2a²+3b²-3a+2b.

7. 20x²+50x.

8. x²+5x+2x+10 = x²+7x+10.
