(a+b)^2= a^2 +2ab + b^2
minus will cit with minus...
minus will cit with minus...
khalsa3:
there is a minus before a
then write the equation as (b-a)^2 nd apply the same formula on it
there s a minus before b too
the ans will be b^2 -2ab + a^2
then minus minus cut nd equation will ne (a+b)^2
check mine then
the ans is a^2+2ab+b^2

it is written as [-1(a+b)]²
thus .. a² + b² + 2ab
thus .. a² + b² + 2ab
# mudrax then we should multiply the ans ie a2 +2ab +b2 with -1 ??
i got d ans
(-a-b)2= (-a)+(-b)whole ^2 which is equalto a2 +2ab +b2
btw thanks mudrax for helping me
