Answer:
The correct option is b.
Step-by-step explanation:
The given polynomial is
[tex]3x^3-3x^2-18x[/tex]
The factors of each term are
[tex]3x^3=3\times x\times x\times x[/tex]
[tex]3x^2=3\times x\times x[/tex]
[tex]18x=2\times 3\times 3\times x[/tex]
The common factors from each term are 3 and x.
[tex]G.C.F.=3\times x=3x[/tex]
Therefore the greatest common factor is 3x. Option b is correct.
