[Maxima] solve(x/sqrt(x+2)=1,x)

[Javier Arantegui]

Dear list,

For me, CAS is like magic. The programs are big black boxes that can
do amazing things, like solving differential equations or really
complex equations.

As I said I don't know a word about how Maxima works, but I find
fascinating that it is incapable of solving this simple equation:

(%i12) eq:x/sqrt(x+2)=1;
(%o12) x/sqrt(x+2)=1

(%i13) solve(eq,x);
(%o13) [x=sqrt(x+2)]


Every high school student knows how to transform this equation to
solve it easily:

(%i14) solve(eq^2,x);
(%o14) [x=2,x=-1]


I just wonder why Maxima is able to solve ODEs but fails with this
simple equation.

Anyway Maxima is fantastic.

Javier
