Question

What is the greatest common factor of the terms in the polynomial 3x3 – 3x2 – 18x?

a. 3
b. 3x
c. 3x2

d. 3x3

Answer 1

The correct answer is 3x

Answer 2

The correct option is b.

Explanation:

The given polynomial is

`3x^3-3x^2-18x`

The factors of each term are

`3x^3=3* x* x* x`

`3x^2=3* x* x`

`18x=2* 3* 3* x`

The common factors from each term are 3 and x.

`G.C.F.=3* x=3x`

Therefore the greatest common factor is 3x. Option b is correct.
