y^{''}-6y^'+9y=30t^2e^{3t}

y^{^{''}} - 6 y^{^{'}} + 9 y = 30 t^{2} e^{3 t}

y = c_{1} e^{3 t} + c_{2} t e^{3 t} + \frac{5 e ^{3 t} t ^{4}}{2}

Solution steps

y^{''} (t) - 6 y^{'} (t) + 9 y = 30 t^{2} e^{3 t}

Solve linear ODE:

y = c_{1} e^{3 t} + c_{2} t e^{3 t} + \frac{5 e ^{3 t} t ^{4}}{2}

y = c_{1} e^{3 t} + c_{2} t e^{3 t} + \frac{5 e ^{3 t} t ^{4}}{2}
