Find the sum or difference. (5a - 3b2 - a) + (b - 5 + 8a2)

5a2 + 4a + b - 5

8a2 - 3b2 + 5a + b - 5

8a2 - 3b2 + 4a + b - 5

8a2 - 3b2 + 4a + b + 5

The answer to your question is the third option

Step-by-step explanation:

Polynomial (5a - 3b² - a) + (b - 5 + 8a²)

1. - Group like terms

(8a²) + (5a - a) + (-3b²) + (b) + (-5)

2. - Simplify

8a² + 4a - 3b² + b - 5

3. - Order the polynomial

Result 8a² - 3b² + 4a + b - 5
