The integral in the image is:

$\int \frac{x^5 + 8x^3 + 7x}{(x^2 - 1)^2} \, dx$

Let's solve this integral step by step.

Step 1: Simplify the integrand

The numerator is $x^5 + 8x^3 + 7x$, which can be factored as $x(x^4 + 8x^2 + 7)$, but this doesn't seem directly helpful. Instead, we will aim for a different strategy using partial fraction decomposition.

We recognize that the denominator is $(x^2 - 1)^2$, which suggests we may need to rewrite the numerator in a way that allows us to use this denominator structure.

Step 2: Set up for partial fraction decomposition

Given the form of the denominator $(x^2 - 1)^2$, we decompose the fraction as follows:

$\frac{x^5 + 8x^3 + 7x}{(x^2 - 1)^2} = \frac{Ax + B}{x^2 - 1} + \frac{Cx + D}{(x^2 - 1)^2}$

We will solve for $A, B, C, D$ and then integrate term by term.

Let me compute these coefficients and continue solving the integral.The integral simplifies to the following expression:

$\frac{(x^2 - 1)(x^2 + 10 \log(x^2 - 1)) - 16}{2(x^2 - 1)}$

This is the antiderivative of the given integral. You can now evaluate it further by plugging in specific bounds (if it's a definite integral) or simplify the result.
