Answer:
The expression in its factored form would be
![3x(x-4)](https://img.qammunity.org/2021/formulas/mathematics/college/aboeebse3ts8y0zrv97xdcy7tl28dvsz0y.png)
Explanation:
We have the expression
![3x^2-12x](https://img.qammunity.org/2021/formulas/mathematics/college/9jlro4dw1yh6j2yunpegpl561pinnf87oo.png)
In order to factor it, we need to find the common terms of each of these.
It can be seen that they both are multiples of 3 and multiples of x.
This means that our factor would be 3x.
