RE: incorrect answer from solve() solving inequality
Thank you, parisse.
For x is negative, it means that each of 1/(x+sqrt(x)), 1/(xsqrt(x)) to be complex number. If so, that is correct. For x is zero, (1/(x+sqrt(x))+1/(xsqrt(x))) = (xsqrt(x) + x + sqrt(x))/(x^2x) = (2x)/(x*(x1)) and this will be equal to 2/(x1) if x<> 0 (otherwise, it will be 0/0) So (1/(x+sqrt(x))+1/(xsqrt(x))) when x=0 should be undefined. However, lim x>0 of (1/(x+sqrt(x))+1/(xsqrt(x))) is 2.
