Simplest Form:

- When its numerator and denominator are relatively prime

1/2, 3/4, 1/8, & 7/100 are all fractions in Simplest Form

4/8, 2/4, 5/100, & 6/36 are NOT in Simplest Form

Chapter 12:


Polynomial:

-A sum of monomials

Examples:
- 6x^2+9x-6
- 9b^4+6b-9
- 5f^5-9f+10

- The 6x^2 is supposed to mean 6x to the 5th power
-The 9b^4 is supposed to mean 9b to the 4th power
- The 5f^5 is supposed to mean 5f to the 5th power




Terms of a Polynomial:

-The monomials that are added together in a polynomial

Examples:

- 9x^2+5x-6

The terms are:

1.) 9x^2

2.) 5x

3.) -6



Binomial:

-A polynomial with 2 terms

Examples:

- 9x^2+6x

- 4z^2+9

- 6a^3+15a


Trinomial:

- A polynomial with 3 terms

Examples:

- 7x^3+5x-9

- 5x^8-9x+6

- 4y^4+8y+4





Degree of a Term:

-The sum of the exponents of the variables in the term

-The degree of a non-zero constant is 0

Example:

Pic_2!.gif



Example_2!.png

The Degree of the term is 7 because the biggest

exponent on the term is 7, therefore the degree is 7.



Degree of a Polynomial:

-The greatest degree of the terms of the polynomial

Example:

Example_11.png




The degree of the polynomial is 2 because the biggest

exponent in the polynomial is 2. Therefore, the degree is 2.




Standard Form (Polynomial):

-A polynomial is written in standard form if all like terms are combined and the terms are

arranged so that the degree of each term decreases or stays the same from left to right
