The sum or difference modeled by the algebra tiles is (-x^2 + 2x + 3) + (-x^2 - 2x - 1) = -2x^2 + 2
<h3>How to determine the sum or difference is modeled by the algebra tiles?</h3>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
