Answer:
![y(x)=C_{1}cos2x+C_{2}sin(2x)](https://tex.z-dn.net/?f=y%28x%29%3DC_%7B1%7Dcos2x%2BC_%7B2%7Dsin%282x%29)
Step-by-step explanation:
It is a linear homogeneous differential equation with constant coefficients:
y" + 4y = 0
Its characteristic equation:
r^2+4=0
r1=2i
r2=-2i
We use these roots in order to find the general solution:
![y(x)=C_{1}cos2x+C_{2}sin(2x)](https://tex.z-dn.net/?f=y%28x%29%3DC_%7B1%7Dcos2x%2BC_%7B2%7Dsin%282x%29)
