### Integration Problem with Detailed Solution

#### Problem:
Evaluate the integral. (Remember to use absolute values where appropriate. Use \( C \) for the constant of integration.)

\[
\int \frac{7}{x^2 - 25} \, dx
\]

#### Solution:
\[ 
\frac{7}{7\sqrt{5}} \left[ \ln|x + 5| - \frac{1}{2} \ln(x^2 - 5x + 25) - \sqrt{3} \, \arctan \left( \frac{2}{5 \sqrt{3}}\left( x + \frac{5}{2} \right) \right)\right] + C 
\]

### Explanation:
The integral provided in the problem consists of a fraction with a polynomial in the denominator. The integration process might involve techniques such as polynomial division, partial fraction decomposition, or trigonometric substitution to simplify and solve the integral.

- **Natural Logarithms**: Observed terms like \(\ln|x + 5|\) and \(\ln(x^2 - 5x + 25)\) indicate the use of natural logarithms in the solution.
- **Arc Tangent Function**: The term involving \(\arctan\) suggests a trigonometric substitution was used during the integration process.
- **Absolute Values**: Note the use of absolute values for the logarithmic terms to ensure the function's domain remains valid.

### Constant of Integration:
Don't forget to add the constant of integration, \( C \), which is a crucial part of any indefinite integral.

This detailed breakdown would help students understand the steps taken to solve the integral and the rationale behind each part of the solution.
