223 Reference ChapterSection R3: PolynomialsPolynomial: a finite sum of terms with only positive or zero integer coefficients permitted for the variables.
The Degree of the polynomial is the highest coefficient.
Monomial: 1 termBinomial: 2 termsTrinomial: 3 terms
Example: Here is a polynomialThe degree is 9, and it is a trinomial

Dividing Polynomials: the quotient can be found using an algorithm similar to the long division model used for whole numbers. Both polynomials must be written in descending order.
Example: What is the quotient of 2730/65?Use the process of long division.
