### factoring 18r^3t^2 + 12r^2t^2 - 6r^2t

I am trying to factor 18r cubed t squared + 12 r squared t squared - 6 r squared t. When I try (3 r squared t + 2t) (6rt -3r), it works out except I get -9r squared t in the middle. Is there any other way to factor this? I'd like an answer as soon as possible. Thank you.

I'm not sure how you're doing your factoring...?

The first step should be taking the common factor out front. With what does this leave you? Is that particularly factorable?

I tried factoring it again and everything checks out except I get -9r cubed t (-9r^3t) in the middle. I want to know how factor the equation so as to get rid of the 9, since it's obviously not in the final answer. Is it (3r^2t +2rt) (6rt -3r) or something else?

What is the reasoning and methodology of your factoring? What are you doing when you're factoring? What are your steps?
