Make {x^2 + y^2 + z^2, x^2 y^2 + x^2 z^2 + y^2 z^2} squares — Part 1

 
 
Find three positive integers   (x, y, z)   to can make the two expressions squares

                                              x^2 \; + \; y^2 \; + \; z^2
                                           x^2 \, y^2 \; + \; x^2 \, z^2 \; + \; y^2 \, z^2

 
 
Here are some solutions:

xy+xz+yz SQ 1
