The factorization of x2 + 3x – 4 is modeled with algebra tiles. an algebra tile configuration. 2 tiles are in the factor 1 spot: 1 is labeled + x, 1 is labeled negative. 5 tiles are in the factor 2 spot: 1 is labeled + x and 4 are labeled +. 10 tiles are in the product spot: 1 is labeled + x squared, 1 is labeled negative x, the 4 tiles below + x squared are labeled + x, and the 4 tiles below the negative x tiles are labeled negative. what are the factors of x2 + 3x – 4?
