This is basically a bug report or feature request, I am posting it here since it seems non-developers are not welcome on the Fricas Github??
Fricas 1.3.5 gives an overcomplicated particular solution for the differential equation here: "solve(D(y(x), x, 3) - 6 * D(y(x), x, 2) + D(y(x), x) - 6 * y(x) = -6 * x^2 + 2 * x, y, x)" Fricas could factor out 36 * x^2 - 74 and then apply the Pythagorean trigonometric identity (sin(x)^2 + cos(x)^2 = 1), giving the much simpler expression x^2 - 2 as the particular solution to the ODE.
