2y^{''}+4y^'+ky=0,y(0)=2,y^'(0)=0

2 y^{^{''}} + 4 y^{^{'}} + k y = 0, y (0) = 2, y^{^{'}} (0) = 0

y = e^{\frac{t ( - 4 + 16 - 8 k )}{4}} (2 + \frac{- - k + 2 + 2}{2 - k}) - \frac{e ^{\frac{t ( - 4 - 16 - 8 k )}{4}} ( - - k + 2 + 2 )}{2 - k}

Solution steps

2 y^{''} (t) + 4 y^{'} (t) + k y = 0

Solve linear ODE:

y = e^{\frac{t ( - 4 + 16 - 8 k )}{4}} (2 + \frac{- - k + 2 + 2}{2 - k}) - \frac{e ^{\frac{t ( - 4 - 16 - 8 k )}{4}} ( - - k + 2 + 2 )}{2 - k}

y = e^{\frac{t ( - 4 + 16 - 8 k )}{4}} (2 + \frac{- - k + 2 + 2}{2 - k}) - \frac{e ^{\frac{t ( - 4 - 16 - 8 k )}{4}} ( - - k + 2 + 2 )}{2 - k}
