Podem continuar por favor!!​

Answer 1

$(x {}^{2} + 2xy + y{}^{2} ) - (x {}^{2} -2 xy + y {}^{2} ) \\ x {}^{2} + 2xy + y {}^{2} - x {}^{2} + 2xy - y {}^{2} \\ 2xy + y {}^{2} + 2xy - y {}^{2} \\ 2xy + 2xy \\ \boxed{\boxed{\boxed{4xy}}}$

$4xy$

Explicação passo-a-passo:

$(x {}^{2} + 2xy + y {}^{2} ) - (x {}^{2} - 2xy + y {}^{2} ) =$

$x {}^{2} + 2xy + y {}^{2} - x {}^{2} + 2xy - y {}^{2} = 4xy$
