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.
