* Identify monomials. *
a number x, y Monomial: An expression that is a constant, a variable, or a product of a constant and variable(s) that are raised to whole number powers. Multiply a number and a variable Exponent can’t be negative! Exponent can’t have fractions!
Is the given expression a monomial: Yes When an equation in one variable is solved the answer is a point on a line. No No

Coefficient of a monomial: The numerical factor in a monomial. Degree of a monomial: The sum of the exponents of all variables in a monomial. Copyright © 2011 Pearson Education, Inc.
Identify the coefficient and degree of each monomial: C: 8 D: 2 C: -1 D: 1 C: one 18 When an equation in variable is solved the answer is a point on a line C: . D: 0 C: 23 = 8 D: 5 -6. 7 D: 3 C: 16 D: 0

Polynomial: A monomial or an expression that can be written as a sum of monomials. Examples: 4 x, 4 x + 8, 2 x 2 - 5 xy + 8 y Polynomial in one variable: A polynomial in which every variable term has the same variable. Example: x 2 – 5 x + 2 Copyright © 2011 Pearson Education, Inc.
Binomial: A polynomial containing two terms. Trinomial: A polynomial containing three terms. Degree of a polynomial: The greatest degree of any of the terms in the polynomial. Copyright © 2011 Pearson Education, Inc.
Identify the type of polynomial and the degree: Binomial D: 2 Monomial D: 3 When an equation in one variable is solved the answer is a point on a line. Trinomial D: 3 Not a polynomial Polynomial D: 3 Polynomial D: 4

Evaluate each of the following: -2(-1)2(4) = -8 (-4)2 – (-4) – 3 = 16 + 4 – 3 = 17 - (-1)2 (2) = - (1)(2) = -2
Combine like terms and write the resulting polynomial in descending order of degree.
