$$5 y{\left(x \right)} - 2 \frac{d}{d x} y{\left(x \right)} + \frac{d^{2}}{d x^{2}} y{\left(x \right)} = 5 x^{2} + 6 x - 12$$
5*y - 2*y' + y'' = 5*x^2 + 6*x - 12

2 x y(x) = -2 + x + 2*x + (C1*sin(2*x) + C2*cos(2*x))*e
$$y{\left(x \right)} = x^{2} + 2 x + \left(C_{1} \sin{\left(2 x \right)} + C_{2} \cos{\left(2 x \right)}\right) e^{x} - 2$$
