How to find the general solution to y"'+2y"-4y'-8y=0?

S_A_V [24]

$y'''+2y''-4y'-8y=0$

has characteristic equation

$r^3+2r^2-4r-8=r^2(r+2)-4(r+2)=(r^2-4)(r+2)=(r-2)(r+2)^2=0$

which has roots at $r=\pm2$ . The negative root has multiplicity 2. So the general solution is

$y=C_1e^{2x}+C_2e^{-2x}+C_3xe^{-2x}$

Answer:

$for\ five\ hours = 300\ min$

Step-by-step explanation:

Given:

Waiting time = 5 hours.

We need to find the number of minutes for 5 hours.

Solution:

We know that 60 minutes for each hour, so one hour is equal to 60 minutes.

For one hour = $60\ minutes$

For five hours = $5\times 60$

$for\ five\ hours = 300\ min$

Therefore, you will have to wait 300 minutes in a line.
