(a+b)²-(a-b)²
(a²+b²+2ab) - (a²+b²-2ab)
a²+b²+2ab- a² -b² +2ab (a² and b² will be cancelled)
4ab
(a²+b²+2ab) - (a²+b²-2ab)
a²+b²+2ab- a² -b² +2ab (a² and b² will be cancelled)
4ab

The value of (a+b)² - (a-b)² is:
= a² + 2ab + b² - ( a² - 2ab + b²)
= a² + 2ab + b² - a² + 2ab - b² ( + and - is cancelled )
= 4ab
= a² + 2ab + b² - ( a² - 2ab + b²)
= a² + 2ab + b² - a² + 2ab - b² ( + and - is cancelled )
= 4ab
