(a+b)²+(a-b)² = 2(a²+b²)
LHS => a²+b²+2ab+a²+b²-2ab
a²+b² a²+b² = 2a²+2b² = 2(a²+b²)
RHS => 2(a²+b²)
hence proved
hope this helps

1.
(2+1)^2 + (2-1)^2=2((2^2)+(1^2))
9+1=2(4+1)
10=2*5
10=10
Hence,solved
2.
(100+10)^2+(100-10)^2=2((100^2)+(10^2))
12100+8100=2(10000+100)
20200=2*10100
20200=20200
Hence,solved
