Answer:
2b²
Step-by-step explanation:
The question asked is a² + 2ab + b² - a² - 2ab + b².
We will first arrange the like terms (terms with similar variables).
We will then get a² - a² + 2ab - 2ab + b² + b².
The a² and 2ab get cancelled out, resulting in
0 + 0 + 2b²
The zeros are not needed, so te answer is 2b²
