EXPLORING ADDING AND SUBTRACTING POLYNOMIALS


	blue	red	green	red	yellow	red

Add and subtract by combining like terms and by using “adding zero” where needed.

	(Add 3 zero pairs of x so you can subtract 3x)

combine like terms

Exploring Polynomial Subtraction

Instructions for pairs:

Partner 1: a. should place algebra tiles that represent a trinomial on the desk.
b. should sketch the tiles in the space provided.
c. should write the resulting trinomial in the space provided.

Partner 2: a. should subtract a few tiles from the desk.
b. sketch what tiles remain in the model.
c. write the resulting polynomial in the space provided.

Repeat this process switching places each time until each person has been partner 1
twice.
