negative m squared plus 5 m plus 1 ​(Simplify your answer. Do not​ factor.)


We are asked to simplify the expression:

\[
-\left(5m^2 - 2m - 5\right) - \left(4 - 3m - 4m^2\right)
\]

Let's go step by step.

### Step 1: Distribute the negative signs
First, distribute the negative sign in both parentheses.

\[
-\left(5m^2 - 2m - 5\right) = -5m^2 + 2m + 5
\]
\[
-\left(4 - 3m - 4m^2\right) = -4 + 3m + 4m^2
\]

### Step 2: Combine the terms
Now we rewrite the entire expression after distribution:

\[
-5m^2 + 2m + 5 - 4 + 3m + 4m^2
\]

Now, let's combine like terms:

- Combine \( -5m^2 \) and \( 4m^2 \): \( -5m^2 + 4m^2 = -m^2 \)
- Combine \( 2m \) and \( 3m \): \( 2m + 3m = 5m \)
- Combine constants \( 5 \) and \( -4 \): \( 5 - 4 = 1 \)

### Final simplified expression:
\[
-m^2 + 5m + 1
\]

This matches the expression given in the problem.
