x^{''}+4x^'+3x=4e^{-2t},x(0)=0,x^'(0)=0

x^{^{''}} + 4 x^{^{'}} + 3 x = 4 e^{- 2 t}, x (0) = 0, x^{^{'}} (0) = 0

x = 2 e^{- t} + 2 e^{- 3 t} - 4 e^{- 2 t}

Solution steps

x^{''} (t) + 4 x^{'} (t) + 3 x = 4 e^{- 2 t}

Solve linear ODE:

x = 2 e^{- t} + 2 e^{- 3 t} - 4 e^{- 2 t}

x = 2 e^{- t} + 2 e^{- 3 t} - 4 e^{- 2 t}
