1. 8.4 Polynomials Find the degree of a polynomial. Arrange the terms of a polynomial in ascending or descending order.

2. What does each prefix mean? mono- bi- tri-

3. What about poly? ________________________________ A polynomial is a monomial or a sum/difference of monomials. Important Note!! An expression is not a polynomial if there is a variable in the denominator.

4. State whether each expression is a polynomial. If it is, identify it. 1)7y - 3x + 4 2)10x 3 yz 2 3)

5. Which polynomial is represented by X2X2 1 1 X X X 1.x 2 + x + 1 2.x 2 + x + 2 3.x 2 + 2x + 2 4.x 2 + 3x + 2

6. The degree of a monomial is the sum of the exponents of the variables. Find the degree of each monomial. 1)5x 2 2)4a 4 b 3 c 3)-3

7. To find the degree of a polynomial, find the largest degree of the terms(monomials). 1) 8x 2 - 2x + 7 Degrees: Which is biggest? 2) y 7 + 6y 4 + 3x 4 m 4 Degrees:

8. Find the degree of x 5 – x 3 y 2 + 4 a)0 b)2 c)3 d)5 e)10

9. A polynomial is normally put in descending order. What is descending order?

10. Put in descending order: 1)8x - 3x 2 + x 4 - 4 2) Put in descending order in terms of x: 12x 2 y 3 - 6x 3 y 2 + 3y - 2x
