y^{''}-y=12x^2+e^x

y^{^{''}} - y = 12 x^{2} + e^{x}

y = c_{1} e^{x} + c_{2} e^{- x} - 12 x^{2} - 24 + \frac{e ^{x} x}{2}

Solution steps

y^{''} (x) - y = 12 x^{2} + e^{x}

Solve linear ODE:

y = c_{1} e^{x} + c_{2} e^{- x} - 12 x^{2} - 24 + \frac{e ^{x} x}{2}

y = c_{1} e^{x} + c_{2} e^{- x} - 12 x^{2} - 24 + \frac{e ^{x} x}{2}
