y^{''}-6y^'+9y=3x^2+4e^{4x}

y^{^{''}} - 6 y^{^{'}} + 9 y = 3 x^{2} + 4 e^{4 x}

y = c_{1} e^{3 x} + c_{2} x e^{3 x} + \frac{x ^{2}}{3} + \frac{4 x + 2}{9} + 4 e^{4 x}

Solution steps

y^{''} (x) - 6 y^{'} (x) + 9 y = 3 x^{2} + 4 e^{4 x}

Solve linear ODE:

y = c_{1} e^{3 x} + c_{2} x e^{3 x} + \frac{x ^{2}}{3} + \frac{4 x + 2}{9} + 4 e^{4 x}

y = c_{1} e^{3 x} + c_{2} x e^{3 x} + \frac{x ^{2}}{3} + \frac{4 x + 2}{9} + 4 e^{4 x}
