I have no idea what to do, my process is chaotic. I arrive at an answer but it doesn't seem to agree with the book.

Your answer looks correct, though the book answer would probably factor it: $(\sqrt{2x}-1)\exp(\sqrt{2x}+3)$. Is that what the difference is?

As to your method, you could just make one substitution, $y = \sqrt{2x}$, rather than making two.
