ok now it's more clear. but the remaining question is.. why they do that manipulation?

comment Problem involving cross products
absolute value?? i thought the $|v \times w|$ was the magnitude of the cross product between v and w is magnitude not absolute value..

comment Distance between a point and a line in space
now i'm studing the prove of this because i like it. i think the softsurfer.com/Archive/algorithm_0102/algorithm_0102.htm is really more clear than the profe in wolfram, even if is geometrical and not algebric. Why they use the derivate of distance to minimize it? And why they use that formula for the square distance?

and | x_2 - x_1 | is vector magnitude or absolute value?

why at (9) there is only x? what about y and z?
