Linear equations of second order with constant coefficients. Find all solutions on $\left(-\infty ,+\infty \right)$. y−4y=0

Willie

The characteristic equation is given by $\left({r}^{2}\right)-4=0$ and has the roots . The general solution is given by
$y={c}_{1}{e}^{2}x+{c}_{2}{e}^{-2}x$ where e1 and e2 are arbitrary costant.
