y^{''}+14y^'+49y=0,y(-4)=5

y^{^{''}} + 14 y^{^{'}} + 49 y = 0, y (- 4) = 5

y = e^{- 7 t - 28} (5 + 4 e^{28} c_{2}) + c_{2} e^{- 7 t} t

Solution steps

y^{''} (t) + 14 y^{'} (t) + 49 y = 0

Solve linear ODE:

y = e^{- 7 t - 28} (5 + 4 e^{28} c_{2}) + c_{2} e^{- 7 t} t

y = e^{- 7 t - 28} (5 + 4 e^{28} c_{2}) + c_{2} e^{- 7 t} t
