Question: Algebra troubles

I am a newcomer to Maple, so I am going to assume that my problems are generally simple, and that I should be posting in this Newbie forum. My apologies in advance if I assumed wrong. My problem is that I take an equation that contains a radical as a common factor for several terms, rearrange it so the radical is on one side, square the equation to remove the radical, and then do a change of variables to convert the equation to a quadratic and solve it. All of that goes well, but when I convert back to the original variable and attempt to verify the solution it becomes very complicated, and I can't seem to simplify it enough to verify the solution. I have tried expand and factor. I have tried simplify. So far everything just makes it more complicated. I appreciate any help you can give. [EDIT]: I am using the file manager to include a condensed version of the worksheet I'm using below. I deleted the parts where I tried to use expand, factor, and simplify commands to accomplish the goal because those parts were messy, but you can feel free to try them. I have been working in classic mode because it works better with grtensor. Download 1995_Diag_VerifySol.mws Again, I appreciate any help. This has been giving me a headache for some time, now. -Jim
