Question

factor out the greatest common factor. if the greatest common factor is 1, just retype the polynomial.
$6r^2 - 12r$

Explanation:

Step1: Identify GCF of coefficients

The coefficients are 6 and 12. Their greatest common factor is 6.

Step2: Identify GCF of variables

The variable terms are $r^2$ and $r$. Their greatest common factor is $r$.

Step3: Factor out overall GCF

The overall GCF is $6r$. Divide each term by $6r$ and write the factored form.
$6r^2 - 12r = 6r(r - 2)$

Answer:

$6r(r - 2)$
