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
