Answer 2

$\huge{\textbf{\textsf{\color{hotpink}{Solution \: :}}}}$

$\huge\tt{(x+y)²+(x-y)²}$

$\large\tt{\color{royalblue}{Apply~formula~:}}$

$\large\tt\boxed{(x+y)²=x²+2xy+y²}$

$\large\tt\boxed{(x-y)²=x²-2xy+y²}$

$\implies\large\tt{\color{royalblue}{(x²+2xy+y²)+(x²-2xy+y²)}}$

$\implies\large\tt{\color{royalblue}{x²+2xy+y²+x²-2xy+y²}}$

$\implies\large\tt{\color{royalblue}{x²+y²+x²+y²}}$

$\implies\huge\red{\underline{\color{red}{\color{red}{\boxed{\tt{\color{royalblue}{2x²+2y²}}}}}}}$
