Subtract: (4a^2+b) - (a2+b) 5a^2 3a^2 + 2b 3a^2 3a^2-2b

The answer to your question is 3a²

Step-by-step explanation:

The correct Polynomial is

(4a² + b) - (a² + b)

Use the law of signs

4a² + b - a² - b

Use the associative property for like terms

(4a² - a²) + (b - b)

Simplify like terms

4a² - a² = 3a²

b - b = 0

Write the result

3a²
