Which model represents the factors of 4x2 – 9? An algebra tile configuration. 5 tiles are in the Factor 1 spot: 2 x , 3 negative. 5 tiles are in the Factor 2 spot: 2 x, 3 negative. 25 tiles are in the Product spot in 5 columns with 5 rows. First row: 2 x squared, 3 negative x. Second row: 2 x squared, 3 negative x. The last 3 rows are the same: 2 negative x, 3 negative.
