y^{''}+5y^'+6y=24e^t+36t^2

y^{^{''}} + 5 y^{^{'}} + 6 y = 24 e^{t} + 36 t^{2}

y = c_{1} e^{- 2 t} + c_{2} e^{- 3 t} + 2 e^{t} + 6 t^{2} - 10 t + \frac{19}{3}

Solution steps

y^{''} (t) + 5 y^{'} (t) + 6 y = 24 e^{t} + 36 t^{2}

Solve linear ODE:

y = c_{1} e^{- 2 t} + c_{2} e^{- 3 t} + 2 e^{t} + 6 t^{2} - 10 t + \frac{19}{3}

y = c_{1} e^{- 2 t} + c_{2} e^{- 3 t} + 2 e^{t} + 6 t^{2} - 10 t + \frac{19}{3}
