I apologize for the mistake. Let me redo the problem:

(5x^2 - 4x -1) - (-4x^2 - 4)

First, we need to distribute the negative sign in front of the second set of parentheses:

(5x^2 - 4x -1) + (4x^2 + 4)

Now, we can combine like terms:

5x^2 + 4x^2 - 4x - 1 + 4

Simplifying further:

9x^2 - 4x + 3

Therefore, the answer is 9x^2 - 4x + 3.
