Question

What is the general solution of the following homogeneous second order differential equation? \frac{d^{2} y}{d x^{2}}+8 \frac{d y}{d x}+15 \cdot y=7 y=A e^{-3 . x}+B e^{-5 . x}+7.0 y=A e^{-3 \cdot x}+B e^{-5 \cdot x}+0.47 y=A e^{-3 \cdot x}+B e^{-5 \cdot x}-7.0 y=A e^{-3 x}+B e^{-5 . x}-0.47
