The general solution of second order differential equation \( \frac{d^2y}{dx^2} + 4\frac{dy}{dx} + 2y = e^x \) is
1
\( y = \frac{C_1}{x} + \frac{C_2}{x^2} + x^2 e^x \).
2
\( y = \frac{C_1}{x} + \frac{C_2}{x^2} + \frac{e^x}{x^2} \)
3
\( y = \frac{C_1}{x} + \frac{C_2}{x^2} + \frac{e^x}{x^3} \)
4
\( y = \frac{C_1}{x} + \frac{C_2}{x^2} + \frac{e^{-x}}{x^2} \)
