☆■■■ Heya,■■■☆ __________________
I guess ! If you area talking about ( a - b )^2, then
Reason = ( a - b ) ^2
= ( a - b )( a - b )
= a ( a - b ) - b ( a - b )
= a^2 - ab - ab + b^2
= a^2 - 2ab + b^2
And if not then ,
( - a - b ) ^2
( -a - b ) ( - a - b )
- a ( - a - b ) - b ( - a - b )
a^2 + ab +ab + b^2
a^2 + 2ab + b^2
Hope It Helps☺!

I have explained bhai...u can see
there is no identity of ( - a - b ) ^2
He has asked formula which states that he want to ask ( a - b )^2
ya no of course there is no identity related to it but we should derive it on the basis of (a-b)^2
no his que is right and my ans is right. ..thanku
I guessed so becz just now he asked ( a+ b )^2
okk no problem. ..nice to meet u.
Me too
thanks .

= a^2 + b^2 + 2 ab.
i hope this ans would helpful to you dude☺
✔so please mark it as brainliest ans..
