A plane with equation xa+yb+zc=1 (a,b,c>0)(adsbygoogle = window.adsbygoogle || []).push({});

together with the positive coordinate planes forms a tetrahedron of volume V=16abc.

Find the plane that minimizes V if the plane is constrained to pass through a point P=(9,6,3) .

HELP!! I have fount the partial derivatives for both of the given equations but I don't know where to go from there!
