4y^{''}+4y^'+y=e^{-x/2}

4 y^{^{''}} + 4 y^{^{'}} + y = e^{- \frac{x}{2}}

y = c_{1} e^{- \frac{x}{2}} + c_{2} e^{- \frac{x}{2}} x + \frac{e ^{- \frac{x}{2}} x ^{2}}{8}

Solution steps

4 y^{''} (x) + 4 y^{'} (x) + y = e^{- \frac{x}{2}}

Solve linear ODE:

y = c_{1} e^{- \frac{x}{2}} + c_{2} e^{- \frac{x}{2}} x + \frac{e ^{- \frac{x}{2}} x ^{2}}{8}

y = c_{1} e^{- \frac{x}{2}} + c_{2} e^{- \frac{x}{2}} x + \frac{e ^{- \frac{x}{2}} x ^{2}}{8}
