y^{''}+7y^'=x+e^{2x}

y^{^{''}} + 7 y^{^{'}} = x + e^{2 x}

y = c_{1} + c_{2} e^{- 7 x} + \frac{x ^{2}}{14} - \frac{x}{49} + \frac{1}{18} e^{2 x}

Solution steps

y^{''} (x) + 7 y^{'} (x) = x + e^{2 x}

Solve linear ODE:

y = c_{1} + c_{2} e^{- 7 x} + \frac{x ^{2}}{14} - \frac{x}{49} + \frac{1}{18} e^{2 x}

y = c_{1} + c_{2} e^{- 7 x} + \frac{x ^{2}}{14} - \frac{x}{49} + \frac{1}{18} e^{2 x}
