(2x-y+3z)(x2+y2+4z2-xy-24z-2xz)=

2x(x2+y2+4z2-xy-24z-2xz)-y(x2+y2+4z2-xy-24z-2xz)+3z(x2+y2+4z2-xy-24z-2xz)=

2x3+2xy2+8xz2-2x2y-48xz-4x2z-y3-4yz2+24yz+2xyz+3y2z+12z3-72z2

     +  xy2-6xz2 - x2y          +3x2z                         -3xyz=

2x3-y3+12z3-3x2y-x2z+3xy2+3y2z-72z2+2xz2-4yz2-48xz+24yz-xyz
