Operations over Polynomials: Adding and Subtracting

Operations over Polynomials: Adding and Subtracting

Where we're going!

• Objective: Apply Operations with Polynomials (adding & subtracting)

  
  

• Standard: APR.1 Add, Subtract, Multiply Polynomials; understand that polynomials form a system analogous to the integers in that they are closed under these operations

• Deliverable: You sould be able to add and subtract polynomials.

Important Concepts

• Apply Order of Operations (PEMDAS)

• Order terms by exxponent in descending order. (x^3 +3x^2-x+5)

• Order variables by alphabetical order. (x^2 + xy + y^2

Multiple Select

Select how polynomials should be correctly written.

• Age Order

• Alphabetcal Order

• Exponents in Descending Order

• Exponents in Ascending Order
