Perform the indicated operations. Write the resulting polynomial in standard form and indicate its degree.

To perform the indicated operations on the polynomials, we will first rewrite the second polynomial \( (2^2 - 3x + 5) \) correctly and then combine all the terms.

1. Rewrite the polynomials:
- First polynomial: \( 5x^2 - 8x - 1 \)
- Second polynomial: \( 2^2 - 3x + 5 \) simplifies to \( 4 - 3x + 5 \), which can be rewritten as \( -3x + 9 \).
- Third polynomial: \( -(x^2 - 5x - 3) \) simplifies to \( -x^2 + 5x + 3 \).

Now, we combine the three polynomials:
\[
(5x^2 - 8x - 1) + (-3x + 9) + (-x^2 + 5x + 3)
\]

2. Combine all the like terms:
- \( 5x^2 - x^2 = 4x^2 \)
- \( -8x - 3x + 5x = -6x \)
- \( -1 + 9 + 3 = 11 \)

So, the resulting polynomial is:
\[
4x^2 - 6x + 11
\]

3. Write it in standard form:
The polynomial in standard form is:
\[
4x^2 - 6x + 11
\]

4. Determine the degree:
The degree of the polynomial is the highest power of \( x \) present, which in this case is:
\[
\text{Degree} = 2
\]

Thus, the final answer is:
- The polynomial: \( 4x^2 - 6x + 11 \)
- The degree: \( 2 \)
