Answer 2

(a+b)^2= (a+b) (a+b)

By further calculations, we get

First term of first bracket multiply by full second bracket

and

second term of first bracket multiply by full second bracket

Now substitute the value in the above mathematical statement:

a(a+b) + b(a+b) =a^2+ab+ba+b^2

a(a+b) + b(a+b)=a^2 + 2ab + b^2.
