What is the general solution of the following homogeneous second-order differential equation? Non-integers are expressed to one decimal place. \frac{d^{2} y}{d x^{2}}-46 . y=0 y=A e^{-6.8 \cdot x}+B e^{6.8 \cdot

x} y=e^{6.8 \cdot x}(A x+B) y=e^{-6.8 . x}(A \cdot \sin (6.8 \cdot x)+B \cdot \cos (6.8 \cdot x)) y=e^{-6.8 \cdot x}(A x+B)
