Answer 2

Let's simplify each expression:

1. $(a+b)^2 + 4a + 4b^2$

To simplify this expression, first expand the square:

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

Now, the expression becomes:

$a^2 + 2ab + b^2 + 4a + 4b^2$

Combine like terms:

$a^2 + 4ab + 5b^2 + 4a$

2. $m - n + m^2 - n^2$

This expression doesn't seem to have any like terms to combine. So, we can just leave it as:

$m - n + m^2 - n^2$

3. $4x^2 - 4xy + y^2 - 16$

This expression doesn't seem to have any like terms to combine either. So, we can leave it as:

$4x^2 - 4xy + y^2 - 16$

4. $xy^4 - 2y^4 - xy + 2y$

Combine the like terms:

$xy^4 - xy - 2y^4 + 2y$

The simplified expression is:

$xy^4 - xy - 2y^4 + 2y$

Note: Please make sure to check the expressions provided, especially the fourth one, as it seems to be missing an operator between $n^2$ and $3$. If you meant something different, please provide the correct expression for a more accurate simplification.
