y^{''}-y^'-2y=-2x^3-3x^2+8x+1

y^{^{''}} - y^{^{'}} - 2 y = - 2 x^{3} - 3 x^{2} + 8 x + 1

y = c_{1} e^{2 x} + c_{2} e^{- x} + x^{3} - x

Solution steps

y^{''} (x) - y^{'} (x) - 2 y = - 2 x^{3} - 3 x^{2} + 8 x + 1

Solve linear ODE:

y = c_{1} e^{2 x} + c_{2} e^{- x} + x^{3} - x

y = c_{1} e^{2 x} + c_{2} e^{- x} + x^{3} - x
