Maybe you meant (a + b)^2 (a plus b all squared).
Then the answer is a^2 + 2ab + b^2.
Oh, you were given that when you last asked. I cannot see any possibilities now that haven't been covered.

yeah, I think you ment (a + b)²
So, first distrubute to get:
(a + b)(a + b)
Now FOIL the above problem to get:
a² + ab + ba + b²
it best to change the middle letters to the same as so:
a² + ab + ab + b²
and do the addition to get
a² + 2ab + b²

(a+b)2 = 2a + 2b
but i have a feeling u migght have meant (a+b)^2
(a+b)^2 = a^2 + b^2 + 2ab

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

Assume this question is:-
(a + b)²
= (a + b).(a + b)
= a² + ab + ba + b²
= a² + ab + ab + b²
= a² + 2ab + b²

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

2(a+b) is the same as
2a + 2b
It is called the distibutive property (because you are "distributing" the 2.)
Hope this helps!

(a+b)2= a2('a' square) + 2ab + b2 ('b' square)
