Question

Factor out the common factor. 3x^3 − 9x

Answer 1

see explanation

Explanation:

Given

3x³ - 9x ← factor out 3x from each term

= 3x(x² - 3) ← in factored form

Answer 2

For this case we have the following expression:

`3x ^ 3-9x`

We must obtain a factored expression.

We look for the factors of 3 and 9:

3: 1.3

9: 1,3,9

Thus, the biggest factor that divides both numbers is 3.

It is noted that "x" is also a common factor of both terms of the expression.

Then, we can rewrite the expression as:

`3x (x ^ 2-3)`

Answer:

`3x (x ^ 2-3)`
