![### Exploring Methods for Integration: An Educational Exercise
#### Integral Problem
Consider the integral below and determine which integration method to use by choosing an appropriate value for \( b \). Assume \( b \neq 0 \) and \( b \) can be positive or negative in the solutions.
\[
\int \frac{1}{x^2 - 6x + b} \, dx
\]
#### Questions
1. **Value of \( b \) for \( u \)-substitution with Power Rule:**
- Determine a value of \( b \) that simplifies the integral so that a \( u \)-substitution method with the power rule is applicable.
2. **Value of \( b \) for \( u \)-substitution with Arctangent:**
- Find a possible value of \( b \) where the integral is conducive to a \( u \)-substitution method resulting in an arctangent function.
3. **Value of \( b \) for Partial Fraction Decomposition:**
- Identify a possible value of \( b \) that makes the integral suitable for a partial fraction decomposition method.
4. **Evaluate Using Partial Fraction:**
- Solve the integral using the \( b \) value found in the previous step that allows for partial fraction decomposition.
#### Instruction
Show detailed calculations for evaluating the integral with each method, specifically focusing on partial fraction decomposition for step 4. Include algebraic manipulation and any relevant substitutions or transformations.
