The answer you are looking for is a² + 2ab + b².

Solution/Explanation:

Writing out the mathematical expression first

(a + b)²

(a + b) (a + b)

a × a = a²

a × b = ab

a × b = ab

b × b = b²

Adding all of these terms together

a² + ab + ab + b²

Combining like terms with "ab" and "ab," to get 2ab.

You will get a² + 2ab + b².

So, therefore, the final answer to this problem is a² + 2ab + b².

Hope that this has helped answer your question for you. Good day.
