1. **State the problem:**
We are given the differential equation $$ty' + 2y = 4t^2$$ with the initial condition $$y(1) = 2$$.
2. **Check the proposed solution:**
The proposed solution is $$y = t^2 + \frac{1}{t^2}$$.
3. **Find the derivative of the proposed solution:**
$$y' = \frac{d}{dt}\left(t^2 + \frac{1}{t^2}\right) = 2t - 2t^{-3}$$.
4. **Substitute $y$ and $y'$ into the differential equation:**
$$t y' + 2y = t(2t - 2t^{-3}) + 2\left(t^2 + \frac{1}{t^2}\right)$$
5. **Simplify the expression:**
$$= 2t^2 - 2t^{-2} + 2t^2 + 2t^{-2}$$
6. **Cancel terms:**
$$= (2t^2 + 2t^2) + (-2t^{-2} + 2t^{-2}) = 4t^2 + 0 = 4t^2$$
7. **Verify initial condition:**
$$y(1) = 1^2 + \frac{1}{1^2} = 1 + 1 = 2$$ which matches the given initial condition.
**Conclusion:** The proposed solution satisfies both the differential equation and the initial condition.
**Final answer:** The solution $$y = t^2 + \frac{1}{t^2}$$ is correct.
