![Page 2: 5-5 Polynomials. Vocab Polynomial- monomial or sum of monomials Monomial- numeral, variable or product of numerals and variables (one term) ex: 4x 3 y](https://reader035.vdocument.in/reader035/viewer/2022071806/56649f515503460f94c74662/html5/thumbnails/2.jpg)
Vocab
Polynomial- monomial or sum of monomials
Monomial- numeral, variable or product of numerals and variables (one term) ex: 4x3y
Binomial- expression with two terms ex: 2x + 6
Trinomials-expression with three terms ex: 3x2 + x – 8
More than 3 terms? We will just call them
polynomials

Degree
Degree of a term: Sum of all exponents in that termEx:
Degree of term: 2+1 or 3
Degree of the polynomial: whichever term has highest degreeEx:
Degree: 4 3 5
The highest is 5 so the polynomial’s degree is 5 and x5 is leading term
yx23
523 62 xyxyx
