### Topic: Integration

#### Problem

Evaluate the integral:

\[
\int \frac{2 - 8x}{\sqrt{49 - 4x^2}} \, dx
\]

#### Solution Approach

To evaluate the given integral, we may need to apply techniques of integration such as substitution, integration by parts, or recognizing standard forms of integrals. Here's a step-by-step guide to approach this integral:

1. **Identify Substitution:**
   Look for a substitution that simplifies the square root expression in the integral.

2. **Simplify the Integrand:**
   Perform the substitution and simplify the integrand, if possible, into a standard form.

3. **Integrate:**
   Use appropriate integration techniques based on the simplified form, such as trigonometric substitution, partial fractions, or integrating known standard forms.

4. **Reverse Substitution:**
   If you used substitution, revert back to the original variable to express the final answer.

The specific steps and simplifications will depend on how the square root can be made into a standard integrable form. 

**Intermediate steps and discussions would be shown here as the solution is worked out.**

Students are encouraged to explore different methods and verify the integral using their understanding of calculus and integration techniques.
