Use a geometric model to factor x2 + 3x + 2 by following these steps:

Step 1: Model the trinomial by placing tiles in the Product section to form a rectangle at the top left. The x2 tile is already in the correct place.

Step 2: Drag tiles to the sections labeled Factor 1 and Factor 2 to represent the factors.

Step 3: What is the factored form of this trinomial?
 (x + 2) (x + 1)
 (x + 3) (x + 2)
 (x + 3) (x + 1)
