You can try the following with substituting b-a with c
var('a,b,c,A,B,C')
eq1 = (sqrt((c)^2 + (B-A)^2) == A+B)
assume(A>0)
assume(B>0)
solve(eq1,c)
which results in
[c == -2*sqrt(A*B), c == 2*sqrt(A*B)]
But can anybody explain me the results of the computation without the assume statements? For A,B both beeing negative the solver does not do anything and for A being bigger and B being smaller then zero, sage throws an error that maxima needs further inputs (the same as when you're not using assume)
