(a+b)^2 = (a+b) × (a+b)

= a(a+b) + b(a+b). [ by algebra rule. ]

= a^2 + ab + ab + b^2

(a+b)^2= a^2 + 2ab + b^2...

Property

$\implies$ ${\boxed{\tt{\blue{(a+b)²=a²+2ab+b²}}}}$

Here when we open the bracket,

$\implies$ we get two brackets

(a+b)(a+b)

Now,

we will multiply

$\implies$a²+ab+ab+b²

$\implies$a²+2ab+b²
