Select the correct answer. Which sum or difference is modeled by the algebra tiles? The figure shows the elimination of 5 red tiles and 5 blue tiles in which two tiles with x and one tile with minus x. A. (x2 − 2x + 3) − (-x2 − 4x − 2) = 2x − 1 B. (x2 − 2x − 3) + (x2 − 4x + 2) = 2x − 1 C. (x2 − 2x − 3) − (x2 + 4x + 2) = 2x − 1 D. (x2 − 2x − 3) + (-x2 + 4x + 2) = 2x – 1

The sum or difference modeled by the algebra tiles is (-x^2 + 2x + 3) + (-x^2 - 2x - 1) = -2x^2 + 2

How to determine the sum or difference is modeled by the algebra tiles?

The tiles that complete the question are added as an attachment

From the attached tiles, we have:

Red tiles = -x^2 + 2x + 3

Blue tiles = -x^2 - 2x - 1

Evaluate the difference

Difference = (-x^2 + 2x + 3) - (-x^2 - 2x - 1)

This gives

(-x^2 + 2x + 3) + (-x^2 - 2x - 1) = -2x^2 + 2
