Answer: -21

Step-by-step explanation:

1. Replace the x and y with the values and solve starting in the parentheses:

12-5 + ((7*(3-23))/5)

12-5 + ((7*(-20)/5)

12-5 + (-140/5)

12-5 + (-28)

7 + (-28)

-21

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

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