Hope It Helps You ✌️

Answer 2

Step-by-step explanation:

(a² + 2ab + b²) – (a² – 2ab + b²) = a² + 2ab + b² – a² + 2ab – b²

Rearrange the terms and you get:

a² – a² + 2ab + 2ab + b² – b²

Cancel out same terms with opposite signs, and you get:

2ab + 2ab

which simplifies to our final answer:

4ab
