This question is related to the Question System of Equations 
eq := {-2*b[2]*B+b[3]*J+b[5]*J-lambda[2]*b[2] = 0, 
          -2*b[5]*B+b[2]*J+b[4]*J-lambda[2]*b[5] = 0, 
          -lambda[2]*b[3]-2*b[3]*B+b[4]*J+b[2]*J = 0, 
          -lambda[2]*b[4]+b[3]*J-2*b[4]*B+b[5]*J = 0, 
           abs(b[2])^2+abs(b[3])^2+abs(b[4])^2+abs(b[5])^2-1 = 0}

 v := {lambda[2], seq(b[i], i = 2 .. 5)}

 ans:=solve(eq,v)

the result show:

          ans:=

why can't produce any result? and some time the system tell me :Warning, solutions may have been lost
