Addition and Subtraction of Multinomial Tiles can be used to model algebraic expression. 1 - tile + x- tile x²- tile + 1-tile -*- tile. -x²- tile Using the tiles, make a model for 2x² + 4x-3 and -3x2-x+2 then find its sum. Solution: 2x2 + 4x -3 + (-3x2 -x + 2) = -x2 + 3x - 1 AA Which tiles are eliminated?what can you say about the tiles that were eliminated?
