The model represents a polynomial and its factors. An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x and 3 are labeled negative. 2 tiles are in the Factor 2 spot: 1 is labeled + x and 1 is labeled negative. 8 tiles are in the Product spot: 1 is labeled + x squared, 4 are labeled negative x, and 3 are labeled +. Which equation is represented by the model? x2 - 2x - 3 = (x - 3) (x + 1) x2 - 4x + 3 = (x - 3) (x - 1) x2 + 2x + 3 = (x + 3) (x - 1) x2 + 4x - 3 = (x + 3) (x + 1)
