D(D-1)^3y=(x^2+2x)e^x

D (D - 1)^{3} y = (x^{2} + 2 x) e^{x}

y = c_{1} + c_{2} e^{x} + c_{3} x e^{x} + c_{4} x^{2} e^{x} + \frac{e ^{x} x ^{5}}{60}

Solution steps

D (D - 1)^{3} y = (x^{2} + 2 x) e^{x}

Solve linear ODE:

y = c_{1} + c_{2} e^{x} + c_{3} x e^{x} + c_{4} x^{2} e^{x} + \frac{e ^{x} x ^{5}}{60}

y = c_{1} + c_{2} e^{x} + c_{3} x e^{x} + c_{4} x^{2} e^{x} + \frac{e ^{x} x ^{5}}{60}
