y^{''}-81y=-243t+162t^2

y^{^{''}} - 81 y = - 243 t + 162 t^{2}

y = c_{1} e^{9 t} + c_{2} e^{- 9 t} - 2 t^{2} + 3 t - \frac{4}{81}

Solution steps

y^{''} (t) - 81 y = - 243 t + 162 t^{2}

Solve linear ODE:

y = c_{1} e^{9 t} + c_{2} e^{- 9 t} - 2 t^{2} + 3 t - \frac{4}{81}

y = c_{1} e^{9 t} + c_{2} e^{- 9 t} - 2 t^{2} + 3 t - \frac{4}{81}
