Question

Factor the following expression using the GCF.

Answer 1

Answer:

$4r(d-4)$

Step-by-step explanation:

$r$ is found in both numbers, so $4r$ is the GCF.

$4dr-16r$

What is $4r$ divided by $4dr$? It would be $d$.

What is $-16r$ divided by $4r$? $-4$.

So, our equation now looks like this:

$4r(d-4)$

So, the last one is correct.

Hope this helps :)
