Question

### Problem 6: Solve the Differential Equation

Given the differential equation:

\[ x^2 y'' + 8xy' + 6y = 0 \]

### Explanation:

This is a second-order linear homogeneous differential equation with variable coefficients. The equation involves the function $ y(x) $, its second derivative $ y'' $, and first derivative $ y' $.

### Solution Approach Overview:

1. **Reduced Form:**
The equation is in a standard form that can be solved using techniques such as the method of Frobenius or transformation to a simpler form using substitution if applicable.

2. **Characteristic Equation:**
Although not directly applicable here due to variable coefficients, a characteristic equation approach could be attempted if the coefficients were constant.

3. **Series Solution (Method of Frobenius):**
This method is suited for differential equations with variable coefficients around a regular singular point. It involves assuming a power series solution and determining coefficients.

4. **Transformation:**
Occasionally, a substitution $ y(x) = x^m \cdot v(x) $ might simplify the equation into one with constant coefficients or another more easily solvable form.

After determining the appropriate path, you can solve for $ y(x) $ using these methods, often involving integration or solving algebraic equations resulting from substitution.
