Exercise 1 Page 60

Let's examine each of the given algebra tiles and what they represent.

We have three tiles that represent x^2, one tile that represents - x, and one tile whose value is 1. By adding these, we can create an algebraic expression modeled by the tiles. x^2+ x^2+ x^2+( - x)+ 1 Finally, we will combine like terms to simplify the above expression. 3 x^2 - x+ 1
