Answer 2

Hi there!

I believe your answer is:  

$a^2+2ab+b^2$

»»————-　★　————-««  

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Calculating the Answer...}}\\\\(a+b)^2\\-------------\\\rightarrow (a+b)(a+b)\\\\---------\\\boxed{\text{Use FOIL.}}\\\\\rightarrow a * a = a ^2\\\rightarrow a * b = ab\\\rightarrow b * a = ba\\\rightarrow b * b = b^2\\---------\\a^2 + ab + ba + b^2\\\\\rightarrow\text{You can rewrite } ba \text{ as } ab. \leftarrow\\\\a^2 + ab + ab + b^2\\\\\rightarrow \boxed{a^2 + 2ab + b^2}$

⸻⸻⸻⸻
