I don't even know where to start on this one. "Find the shortest distance from the point (1,0,-2) to the plane x+2y+z=4"

It's the distance along the normal to the plane, x+2y+z=4. Do you know how to find a vector normal to that plane?
Is it the cross product of the partial derivative of x and partial derivative of y? And then the magnitude of that?

(1) ... so that the squared distance from the point (1,0,-2) is... (2) Now You minimize respect to x and y and the problem is solved... Kind regards
