NO CLUE
we know that ,[\(a+b)^{2} = a ^{2}+2ab+b ^{2} \] now we can see that \[a ^{2}+2ab+b ^{2} is definitely greater than the a ^{2}+b ^{2} .\] Becuz it has extra value that is "2ab " .

but when you expand it out dont you also get the 2ab for the second one?
yeah! you r right . Thant's why the 1st one is greater . It has a^2 and B^2 also with 2ab . But the 2nd one only have a^2 and B^2 but no 2ab
yea but I'm saying when you expand out |dw:1442947717914:dw|
then ?
so it makes it equal no?
