Linear equations of second order with constant coefficients. Find all solutions on (−∞,+∞). y−4y=0

Question

Willie · Accepted Answer

The characteristic equation is given by (r2)−4=0 and has the roots r1=2 and r2=−2. The general solution is given by y=c1e2x+c2e−2x where e1 and e2 are arbitrary costant.
