Answer 2

Answer:

please marks as brainliest answer

Step-by-step explanation:

when can we this question like this , that

(a+b)(a+b)

then multiply this equation

a(a+b) +b(a+b)

a^2+ab + ba + b^2 { a^2 and b^2 means that a square and b square)

a^2 + 2ab + b^2. { ab+ba = 2ab}

so this we be

(a+b)^2 { this means whole square of a+b }

and we all know that (a+b)^2 = a^2+2ab+b^2
