For Algebra II
We're learning about solving roots using synthetic division. Currently I am stuck on one problem which is x^3-4x^2-36x-48=0
My teacher suggested for these problems to "guess and check" by using the last term and the first, but I don't really understand the concept when the ending term is larger.
Please help! :)
Thanks.

I'm actually not sure how to find which roots, but I normally like to start with 1 and -1 first
