$\huge \blue{q} \red{u} \green{e} \pink{s} \purple{t} \orange{i}o\red{n}$

what is the Value of (a+b)² - (a-b)²

$\huge\blue{a} \red{n} \green{s} \pink{w} \purple{e} \orange{r}$

$\huge \bold \red{4ab}$

Step-by-step explanation:

$\huge\blue{s} \red{o} \green{l} \pink{u} \purple{t} \orange{i} \red{o}n$

$\bold \blue{using\: identify :- (a+b)² = a²+b²+2ab \:and \:(a-b)² = a²+ b² - 2ab}$

$(a+b)² - (a-b)² \\ = {a}^{2} + {b}^{2} + 2ab - \\ ({a}^{2} + {b}^{2} - 2ab) \\ = {a}^{2} + {b}^{2} + 2ab - \\ {a}^{2} - {b}^{2} + 2ab \\ = 2ab + 2ab \\ = 4ab$
