Answer:
Using synthetic division suffices to answer your question:
Step-by-step explanation:
Synthetic division is the process by one reduces a large polynomial in your case by a binomial in your case
.
To do so one does the following:
Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:
Which can be factored in the following, and I will provide the complete factorization as well:
