Answer:
10a²+5ab+2b²
Step-by-step explanation:
Start by combining like terms aka the ones that match:
Step 1: (4a²-5ab-6b²) + (10ab+6a²+8b²)
Step 2: (10a²-5ab-6b²) + (10ab+8b²)
Step 3: (10a²+5ab-6b²+8b²)
Final answer: 10a²+5ab+2b²
In step 1, I added the 4 and 6. In step 2, I added -5 and 10. In step 3, I added -6 and 8. For each I attached the proper ending (a², ab, and b²).
I hope this clears some confusion!
