25y^{''}+90y^'+81y=0

25 y^{^{''}} + 90 y^{^{'}} + 81 y = 0

y = c_{1} e^{- \frac{9 t}{5}} + c_{2} e^{- \frac{9 t}{5}} t

Solution steps

25 y^{''} (t) + 90 y^{'} (t) + 81 y = 0

Solve linear ODE:

y = c_{1} e^{- \frac{9 t}{5}} + c_{2} e^{- \frac{9 t}{5}} t

y = c_{1} e^{- \frac{9 t}{5}} + c_{2} e^{- \frac{9 t}{5}} t
