The galois group being S(6), the polynomial is not solvable.

Why don't you try it yourself first? Then, if you have any problems, post a Reply.

By the way, you should remove with(linalg). That is a very old package that is not meant to be used anymore.

There's no need to apologize. I realize that there's no easy way to avoid multiple answering, and I enjoy seeing a different presentation of essentially the same answer. Anyway, you have the additional information about Explore, which was educational for me.

If someone simul-posts an Answer that seems significantly better than mine, I usually delete mine.

Warning: The worksheet attached to the Question has a single expression that is 3753 pages long.

@maplelearner Note that your variable RootOfLambda has two parts. One of the roots is 0. Your eval statement should be eval(P, lambda= RootOfLambda[2]) so that you select only the second root. At this point, you can continue working with the P expression, even though it contains RootOfs. For example, you can set it to 0 and solve it, getting three simple solutions with no RootOfs.

Numerical solution will not be possible because of your four symbolic constants.

The RootOf is a degree 6 polynomial with symbolic coefficients. Since it's polynomial, it is not considered transcendental, for whatever that's worth. Still, I don't have much hope for simplifying it.

@acer Thanks, I found it.

Thank you for your response. Let's consider the worksheet with embedded components that was under discussion on this forum yesterday, which I include here for convenience: test.mw

When I do as you suggest on the slider in the upper left, the only code that I see is test:-suwak();. I can't find any other spot on the worksheet that has a context menu with the entry Edit Value Changed Action. Where am I going wrong?

And how does one access the Startup and/or Code Edit Regions?

There are many possible causes for this error. It just means that Maple's kernel process has died. For me, it usually seems related to a computation getting too large or out of control. Unless the message occurs within a few seconds of opening Maple, I seriously doubt that it has anything to do with firewalls.

@maplelearner Please upload a worksheet. A RootOf doesn't necessarily mean that the equation is transcendental, nor does it necessarily mean that there is only the possibility of a numeric solution. You should be proceed with the RootOf as far as you can.
