It looks like the image contains a set of algebraic expressions that need to be simplified. Let me break down the steps for you. I'll go ahead and start with the first expression from the list.

Problem (1):
$4a^2 - 3b^2 + 2ab + (4a^2 - 4b^2)$

To simplify this, first remove the parentheses and combine like terms:

$4a^2 - 3b^2 + 2ab + 4a^2 - 4b^2$

Now, combine the terms with $a^2$ and the terms with $b^2$:

$(4a^2 + 4a^2) + (-3b^2 - 4b^2) + 2ab$

This simplifies to:

$8a^2 - 7b^2 + 2ab$

So, the simplified expression is: $8a^2 - 7b^2 + 2ab$
