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 What does each prefix mean?:
What does each prefix mean? mono one bi two tri threeWhat about poly?:
What about poly? one or more 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.State whether each expression is a polynomial. If it is, identify it.:
State whether each expression is a polynomial. If it is, identify it. 1) 7y - 3x + 4 trinomial 2) 10x 3 yz 2 monomial 3) not a polynomialWhich polynomial is represented by :
Which polynomial is represented by X 2 1 1 X X X x 2 + x + 1 x 2 + x + 2 x 2 + 2x + 2 x 2 + 3x + 2 I’ve got no idea!The degree of a monomial is the sum of the exponents of the variables. Find the degree of each monomial.:
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 8 -3 0To find the degree of a polynomial, find the largest degree of the terms.:
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 is the degree! 2) y 7 + 6y 4 + 3x 4 m 4 Degrees: 7 4 8 8 is the degree!Find the degree of x5 – x3y2 + 4:
Find the degree of x 5 – x 3 y 2 + 4 0 2 3 5 10A polynomial is normally put in ascending or descending order.:
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.Put in descending order::
Put in descending order: 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 + 3y3) Put in ascending order in terms of y: 12x2y3 - 6x3y2 + 3y - 2x:
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 Put in ascending order: 5a 3 - 3 + 2a - a 2 -3 + 2a - a 2 + 5a 3Write in ascending order in terms of y: x4 – x3y2 + 4xy – 2x2y3:
Write in ascending order in terms of y: x 4 – x 3 y 2 + 4xy – 2x 2 y 3 x 4 + 4xy – x 3 y 2 – 2x 2 y 3 – 2x 2 y 3 – x 3 y 2 + 4xy + x 4 x 4 – x 3 y 2 – 2x 2 y 3 + 4xy 4xy – 2x 2 y 3 – x 3 y 2 + x 4
