(1/4)y^{''}+y^'+y=x^2-2x

Solução

(\frac{1}{4}) y^{^{''}} + y^{^{'}} + y = x^{2} - 2 x

y = c_{1} e^{- 2 x} + c_{2} x e^{- 2 x} + x^{2} - 4 x + \frac{7}{2}

Passos da solução

(\frac{1}{4}) y^{''} (x) + y^{'} (x) + y = x^{2} - 2 x

Solve linear ODE:

y = c_{1} e^{- 2 x} + c_{2} x e^{- 2 x} + x^{2} - 4 x + \frac{7}{2}

y = c_{1} e^{- 2 x} + c_{2} x e^{- 2 x} + x^{2} - 4 x + \frac{7}{2}

\frac{d x}{1 - x ^{2}} = \frac{d y}{1 - y ^{2}}
