What do these prefixes mean? Can you give a word that starts with them? MONO BI TRI POLY
Term A number, a variable, or the product/quotient of numbers/variables. Examples?
Degree of a Term The exponent of the variable. We will find them only for one-variable terms.
Term Degree of Term 3 0 4 x 1 -5 x 2 2 18 x 5 5
Polynomial A term or the sum/difference of terms which contain only 1 variable. The variable cannot be in the denominator of a term.
Degree of a Polynomial The degree of the term with the highest degree.
Polynomial Degree of Polynomial 6 x 2 - 3 x + 2 2 15 - 4 x + 5 x 4 4 x + 10 + x 1 x 3 + x 2 + x + 1 3
Standard Form of a Polynomial A polynomial written so that the degree of the terms decreases from left to right and no terms have the same degree.
Not Standard 6 x + 3 x 2 - 2 3 x 2 + 6 x - 2 15 - 4 x + 5 x 4 - 4 x + 15 x + 10 + x 2 x + 10 1 + x 2 + x 3 x 3 + x 2 + x + 1
Naming Polynomials are named or classified by their degree and the number of terms they have.
Polynomial Degree Name 7 0 constant 5 x + 2 1 linear 4 x 2 + 3 x - 4 2 quadratic 6 x 3 - 18 3 cubic For degrees higher than 3 say: “nth degree” x 5 + 3 x 2 + 3 x 8 + 4 “ 5 th degree” “ 8 th degree”
