y^{''}-4y^'-3y=8e^x

y^{^{''}} - 4 y^{^{'}} - 3 y = 8 e^{x}

y = c_{1} e^{(2 + 7) x} + c_{2} e^{(2 - 7) x} - \frac{4}{3} e^{x}

Solution steps

y^{''} (x) - 4 y^{'} (x) - 3 y = 8 e^{x}

Solve linear ODE:

y = c_{1} e^{(2 + 7) x} + c_{2} e^{(2 - 7) x} - \frac{4}{3} e^{x}

y = c_{1} e^{(2 + 7) x} + c_{2} e^{(2 - 7) x} - \frac{4}{3} e^{x}
