y^{''}-2y^'-3y=-3e^{-x}

y^{^{''}} - 2 y^{^{'}} - 3 y = - 3 e^{- x}

y = c_{1} e^{3 x} + c_{2} e^{- x} + \frac{3 e ^{- x} x}{4}

Solution steps

y^{''} (x) - 2 y^{'} (x) - 3 y = - 3 e^{- x}

Solve linear ODE:

y = c_{1} e^{3 x} + c_{2} e^{- x} + \frac{3 e ^{- x} x}{4}

y = c_{1} e^{3 x} + c_{2} e^{- x} + \frac{3 e ^{- x} x}{4}
