To solve the equation \(\frac{x^4 + x^3 - 5x^2 - 2x - 1}{x^2 - 1} = 2x + 1\) using the graph, let's analyze the given image.

### Steps:
1. **Understand the equation**: The problem involves finding the roots (solutions) where the two functions intersect. The given equation is \(\frac{x^4 + x^3 - 5x^2 - 2x - 1}{x^2 - 1} = 2x + 1\).

2. **Graph Interpretation**: 
   - The blue curve corresponds to the function \(\frac{x^4 + x^3 - 5x^2 - 2x - 1}{x^2 - 1}\).
   - The green curve represents the line \(2x + 1\).
   
3. **Intersection Points**:
   - The solutions to the equation are the \(x\)-values where the blue and green curves intersect.

### Checking the provided options:
- **a) \(x = 2\)**: Check if there's an intersection at \(x = 2\).
- **b) \(x = -0.41\) or \(x \approx 2.41\)**: Look for intersections near these \(x\)-values.
- **c) \(x = -1\) or \(x = 0.5\)**: Verify intersections at \(x = -1\) and \(x = 0.5\).
- **d) \(x = -1\)**: See if there's an intersection at \(x = -1\) only.

### Analysis:
- From the graph, intersections occur approximately at \(x = -1\) and \(x = 0.5\).

Given this analysis, **the correct answer is option c)**: \(x = -1\) or \(x = 0.5\).
