What are the official, mathematical names for polynomials with more
than three terms?  For example, a polynomial with one term is a
monomial, with two terms is a binomial, and with three terms is a
trinomial.  What is a polynomial with more than three terms called?

Hi, Beth.

A polynomial of four terms is sometimes called a quadrinomial, but
there's really no need for such words.  That's because the number of
terms in a polynomial is not important.  There are special techniques
for factoring quadratic trinomials, which is why that term is used;
sometimes a quadrinomial is worth mentioning for the same reason, but
beyond that, a polynomial is just a polynomial, and the degree is more
important than how many terms happen to be non-zero.

If you have any further questions, feel free to write back.
