Question

expand the given identies (x+y)2​

Answer 1

(x+y)2

2x+2y

Hence 2x +2y is the answer mate

Answer 2

Answer:

$\huge{\dag}{\underline{\boxed{\sf{\red{Answer:- }}}}}$

$(x + y) ^{2} \\ (x + y)(x + y) \\ x(x + y) + y(x + y) \\ {x}^{2} + xy + xy + {y}^{2} \\ Add \: like \: terms \: and \: we \: get: \\ {x}^{2} + 2xy + {y}^{2} \\ Rearrange \: the \: terms \: and \: we \: get: \\ {x}^{2} + {y}^{2} + 2xy$

Hence in this way we obtain the identity as trinomial i.e 3 terms x², y² and 2xy.
