Answer 1

Step-by-step explanation:

HERE'S THE ANSWER☑

$({x + y})^{2} = (x - y) {}^{2} +4 xy \\ (x + y) {}^{2} = (x) {}^{2} + {y}^{2} - 2xy + 4xy \\ (x + y) {}^{2} = {x}^{2} + {y}^{2} + 2xy \\ (x + y) {}^{2} = (x + y) {}^{2} \\ lhs = rhs \\ \: \: \: \: \: \: \: \: \: \: hence \: proved...$

And identities used Are-

• (a-b)*2 = (a)*2 + (b)*2 - 2ab
• (a+b)*2 = (a)*2 + (b)*2 + 2ab
