Question

How do you factor 3x^2-12x?

Answer 1

`3x(x - 4)`

Explanation:

In a case like this where there are only two terms, you can start by just taking out the common factor, which in this case is `3x`.
`3x^2 - 12x = 3x(x - 4)`
If the complete expression is `3x^2 - 12x = 0` then either`x=0` or `x=4`

Answer 2

See a solution process below:

Explanation:

First, rewrite the expression as:

`(3x * x) - (3x * 4)`

Now, factor a `3x` out of each term:

`3x(x - 4)`

Answer 3

`3x(x-4)`

Explanation:

`3x^2-12x`

Factor out the GCF using the distributive property

`3x(x-4)`

Answer 4

`3x(x-4)`

Explanation:

`"take out a "color(blue)"common factor "3x`

`=3x(x-4)`

Answer 5

`3x(x-4)`

Explanation:

There are two terms in the expression and there is a common factor of `3x` in both of them.

Divide the common factor out of each and the coefficients of `3x`
are written in the bracket:

`3x^2-12`

`=3x(x-4)`

This gives us two factors: `3x and (x-4)`
