2 Monomials definedA number like 6, 10, or 958(called a constant or a constant monomial)A variable like x, y, or zA product ( that means multiply) of a number and one or more variables
3 Polynomials Definition: the sum of monomials Special names: Binomial: is the sum of two termsxy + 3xTrinomial: is the sum of three termsa + ab + 6
4 Some examples of Monomials Like Terms7xyz, 9xyz, and ½xyz6x, 5x, and 102xUnlike Terms9x and 4 y3ab, 3 bc, and 8 abc
5 Adding Monomials is Magic!!! When monomials have exactly the same variables including the same exponents they are called LIKE TERMSLIKE TERMS can be added by adding their coefficients
6 Monomials AddedNotice that the coefficients are added but the variable and the exponent remain the same.
7 More Monomials AddedBe sure to compare variables and exponents before adding coefficientsThey must be exactly the sameIf they are not LEAVE THEM ALONE
8 DegreeOf a variableThis just means the number of times the variable occurs as a factor in the monomialThe x is of degree 2Of a monomialThis means the sum of the degrees of the variablesThe degree ofis = 7
9 NoteThe degree of any non zero constant monomial such as 12 is 0
10 The Degree of a Polynomial Is the greatest of the degrees of its terms after it has been simplified.
