1
Messin with Monomials Hey whatz a monomial???

2
Monomials defined A number like 6, 10, or 958(called a constant or a constant monomial) A variable like x, y, or z A 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 terms xy + 3x Trinomial: is the sum of three terms a + ab + 6

4
**Some examples of Monomials**

Like Terms 7xyz, 9xyz, and ½xyz 6x, 5x, and 102x Unlike Terms 9x and 4 y 3ab, 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 TERMS LIKE TERMS can be added by adding their coefficients

6
Monomials Added Notice that the coefficients are added but the variable and the exponent remain the same.

7
More Monomials Added Be sure to compare variables and exponents before adding coefficients They must be exactly the same If they are not LEAVE THEM ALONE

8
Degree Of a variable This just means the number of times the variable occurs as a factor in the monomial The x is of degree 2 Of a monomial This means the sum of the degrees of the variables The degree of is = 7

9
Note The 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.

11
Monomials Multiplied To multiply these monomials Rearrange

12
**Rule for Multiplying Monomials**

It’s easy. Just remember to ADD the Exponents

13
**Monomial Raised to a Power**

This means to repeatedly multiply the monomial So Means

14
**Rule for Raising Monomials to a Power**

It’s easy. Just remember to Multiply the Exponents
