### Differential Equation Problem

**2. Consider the equation**

\[ t^2 x'' + 2t x' - 6x = t^2. \tag{1} \]

**(a)** Show that \( x_1(t) = t^2 \) and \( x_2(t) = t^{-3} \) are independent solutions to the homogeneous equation 

\[ t^2 x'' + 2t x' - 6x = 0. \]

That is, demonstrate that each is a solution and verify the Wronskian is non-zero.

**(b)** Solve (1) using the variation of parameters. **Hint:** Don’t forget to make the coefficient on the \( x'' \) term one before you start.
