he factorization of a trinomial is modeled with algebra tiles.

An algebra tile configuration. 3 tiles are in the Factor 1 spot: 1 is labeled + x, 2 are labeled negative. 4 tiles are in the Factor 2 spot: 1 is labeled + x and 4 are labeled +. 12 tiles are in the Product spot: 1 is labeled + x squared, 2 are labeled negative x, the 3 tiles below + x squared are labeled + x, and the 6 tiles below the negative x tiles are labeled negative.
Which trinomial is factored?

x2 + 3x – 6
x2 + 5x – 6
x2 + 3x – 2
x2 + x – 6
