Ecuación diferencial y’’+2y’+5y=e^2x(9x-7)
El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
2 2 2 2
52*e -x 71*x*e 9*x *e
y(x) = ----- + (C1*sin(2*x) + C2*cos(2*x))*e - ------- + -------
125 25 5
$$y{\left(x \right)} = \frac{9 x^{2} e^{2}}{5} - \frac{71 x e^{2}}{25} + \left(C_{1} \sin{\left(2 x \right)} + C_{2} \cos{\left(2 x \right)}\right) e^{- x} + \frac{52 e^{2}}{125}$$
