Question

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

Answer 1

The correct answer is 3x

Answer 2

Answer:

The correct option is b.

Step-by-step explanation:

The given polynomial is

$3x^3-3x^2-18x$

The factors of each term are

$3x^3=3\times x\times x\times x$

$3x^2=3\times x\times x$

$18x=2\times 3\times 3\times x$

The common factors from each term are 3 and x.

$G.C.F.=3\times x=3x$

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