Hello, I have been struggling to find the k value and recurrence relation for this differential equation using the Frobenius method. Could I please get some help to better understand the learning process?
![### Finding a Solution Using the Method of Frobenius
#### Differential Equation:
\[ 9x^2y'' + 6x^2y' - (x + 4)y = 0 \]
#### Note:
Use the positive value of \( k \) for your answer below.
#### Series Solution:
\[ y = a_0 x^k + a_1 x^{k+1} + a_2 x^{k+2} + a_3 x^{k+3} + \cdots \]
#### Where:
\[ k = \frac{2}{3} \]
#### And:
\[ a_n = \left( \frac{-6n}{9n^2 + n} \right) a_{n-1} \]
#### For:
\[ n \geq 1 \]
This transcription includes the mathematical formulation and rearranges the original content into a structured format suitable for educational purposes.
