Answer:

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:

Divide x^4+x^3+7x^2-6x+8 by x+2+2x+8 using long polynomial division.
Answer:
x^2-x+1
