17h	comment	Find all the integer numbers $a$, $b$, $c$, $d$, $e$, $f$, $k$ to this equation have three integer different solutions? I have just edited $[-10,10]$. I want only integer solutionS. I think, $x$ depend on parameters.

2d	comment	Find all the integer numbers $a$, $b$, $c$, $d$, $e$, $f$, $k$ to this equation have three integer different solutions? My code is $[-10,10]$, and ofcourse, it can $[-10,10]$; $k$ is parameter and $x$ is a unknown.

Apr 28	comment	How to find the minimum of this constrained expression? @belisarius I did so. Thank you.
Apr 28	comment	How to find the minimum of this constrained expression? My problem is Minimize[{1/2 (x^2 y^2 + y^2 z^2 + z^2 x^2) + 96/(x + y + z + 1), x >= 0 && y >= 0 && z >= 0 && x^2 + y^2 + z^2 == 5}, {x, y, z}]. But I typed wrong.
