here is trinomial with a 4th term
could be just
now we can factor out x and 4 and get groups
we need the 4th term in order to do this.
now we can factor out and get
however you can factor
directly without doing the grouping
hope this helps??
New math class with some new questions. I have defined number one, but I need feedback for number two, please.
Thanks in advance for the assistance.
1. What is a trinomial?
A = In algebra, a trinomial is a polynomial consisting of three terms or three monomials.
2. When factoring a trinomial by grouping, why is it necessary to write the trinomial in four terms? Provide an example.

Bigwave,
Thanks for the quick response. Your examples are very helpful.
Part of the question is "why is it necessary to write the trinomial in four terms?" Is there some rule that gives the answer to this? I don't know the answer to this part of the question.
Thanks again.
