Using Tiles to Multiply a Monomial by a Binomial Try-It Multiply 3x (2x 1) by following these steps: Step 2: Drag tiles to the section labeled Factor 2 to represent the factor 2x - 1. Step 3: Complete the model by dragging tiles to create a rectangle in the section labeled Product that represents the product of these factors. Step 4: What is the product of these two binomials? O x2-3x O -x+3x O 6x2 - 3x The correct tiles are now in place
