5 / 3 / 2

Use a geometric model to factor 2x2 - x -1 by following these steps:

Step 1: Place two big square tiles horizontally. Place a red long tile to the right of the big square tiles. Step 2: Place two blue long tiles underneath the big square tiles. Place a small blue square to the right of the two blue long tiles. Step 3: Place two long red tiles above the bog square tiles, horizontally. Place a long red tile to the left of the big square tiles, then place a small blue square underneath that. Step 4: B

Use geometric model to factor 3x2 + 4x +1 by following these steps:

Step1: Place 3 big square tiles in a row horizontally. Place a long tile under each big square tile. place one long tile to the right of the big square tiles, then place a small square tile underneath that. Step 2: Place three long tiles above the big square tiles. place a small square tile to the right of the long tiles. Place a long tile to the left of the big square tiles, then place a small square tile under that. Step 3: B
