d
4*--(y(x)) 2
dx 4*y(x) d *y(x) 2 2*x
- ---------- + ------ + ------- = 8*x *e *sin(2*x)
dx dx 3
dx
$$\frac{d^{2} y{\left(x \right)}}{dx^{3}} + \frac{4 y{\left(x \right)}}{dx} - \frac{4 \frac{d}{d x} y{\left(x \right)}}{dx} = 8 x^{2} e^{2 x} \sin{\left(2 x \right)}$$
d^2*y/dx^3 + 4*y/dx - 4*y'/dx = 8*x^2*exp(2*x)*sin(2*x)
