1 Objectives The student will be able to: 1. find the degree of a polynomial. 2. arrange the terms of a polynomial in ascending or descending order. SOL: none Designed by Skip Tyler, Varina High School

2 What does each prefix mean? mono one bi two tri three

3 What about poly? one or more A polynomial is a monomial or a sum/difference of monomials. Remember, 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 trinomial 2) 10x 3 yz 2 monomial 3) 5/2y 2 + 7y not a polynomial

5 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

6 To find the degree of a polynomial, find the largest degree of the terms. 1) 8x 2 - 2x + 7 Degrees: 2 1 0 Which is biggest? 2! 2) y 7 + 6y 4 + 3x 4 m 4 Degrees: 7 4 8 8 is the degree!

7 A polynomial is normally put in ascending or descending order. What is ascending order? Going from small to big exponents. What is descending order? Going from big to small exponents.

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

9 3) Put in ascending order in terms of y: 12x 2 y 3 - 6x 3 y 2 + 3y - 2x -2x + 3y -6x 3 y 2 + 12x 2 y 3 4) Put in ascending order: 5a 3 - 3 + 2a - a 2 -3 + 2a - a 2 + 5a 3
