Hey user here is your answer......

--->Identity (+a+b)^2

---->(a+b)^2=a^2+2ab+b^2

◆Here a= -a

So put in identity

◆(-a+b)^2=(-a)^2+2(-a)(b)+(b)^2

◆(-a+b)^2=a^2-2ab+b^2

Answer 2

Hey!!
.
.
Here the following is applied:
➡(a+b)^2

When we expand this, it'll become:
➡(-a)^2 + (b)^2 + 2ab.
➡a^2 + b^2 +2ab. that's equals to (a+b)'s whole square.☺
