Please do number 5
**4.** Consider the equation \( x'' - 2ax' + a^2x = 0 \), which has solution \( x = e^{at} \). Use reduction of order to find a second independent solution. (This shows the origin of the \( te^{at} \) solution in a second-order linear equation with constant coefficients, in the real, equal eigenvalue case.)

**5.** One solution of 

\[
x'' - \frac{t+2}{t}x' + \frac{t+2}{t^2}x = 0
\]

is \( x_1(t) = t \). Find a second independent solution.
