An algebra configuration where the largest tile is labeled negative x squared, 3 tiles are labeled plus x, where each tile is half the size of the largest tile, and 4 tiles labeled minus that are one-quarter the size of the largest tile.
Which polynomial represents the algebra tile configuration shown?

x2 + 3x + 4
x2 + 3x − 4x
−x2 − 7
−x2 + 3x − 4

Step-by-step explanation:

An algebra tile configuration. There are 3 large tiles, 5 tiles each half the size of a large tile, and 8 tiles each one-quarter the size of a large tile. Two of the large tiles are labeled plus x squared and 1 is labeled negative x square. Two smaller tiles are labeled plus x and 3 are labeled negative x. Six of the smallest tiles are labeled + and 2 are labeled minus.

Which polynomial is represented by the algebra tiles?

x2 – x – 4

x2 – x + 4

3x2 – 5x + 8

3x2 – 5x – 8

Answer:

D.  (−x2 + 3x − 4)
