Using the remainder theorem, substitute 6 in for any x in the equation and it will equal the remainder if it has been divided by (x-6). If the remainder is zero, then it would have divided evenly...making it a factor. If it equals anything but zero then it would not be a factor

X-6=0,x=6
put x=6 in the given eq. 3 x^{3} -16 x^{2} -72=3( 6^{3} )-16( 6^{2} )-72
=3(216)-16(36)-72

=648-576-72
=648-648
=0
hence x-6 is a factor of the given polynomial
