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 $x = 0.5$.
