y^{''}+3y^'+2y=4x^2

y^{^{''}} + 3 y^{^{'}} + 2 y = 4 x^{2}

y = c_{1} e^{- x} + c_{2} e^{- 2 x} + 2 x^{2} - 6 x + 7

Solution steps

y^{''} (x) + 3 y^{'} (x) + 2 y = 4 x^{2}

Solve linear ODE:

y = c_{1} e^{- x} + c_{2} e^{- 2 x} + 2 x^{2} - 6 x + 7

y = c_{1} e^{- x} + c_{2} e^{- 2 x} + 2 x^{2} - 6 x + 7
