Mathematics
1 answer:
Anni [7]3 years ago
7 0

Answer:

Option A) (-x^2 - 2x + 4)-(x^2 + 2x +1)= -2x^2-4x +3 is modeled by the algebra tiles

Step-by-step explanation:

Given (-x^2 - 2x + 4)-(x^2 + 2x +1)= -2x^2-4x + 3

To verify that the given sum or difference is modeled by the algebra tiles

Now applying the algebraic sum operations we get

(-x^2 - 2x + 4)-(x^2 + 2x +1)=-x^2 - 2x + 4 - x^2 - 2x -1

= -2x^2-4x + 3   ( using algebraic sum operations )

Therefore (-x^2 - 2x + 4)-(x^2 + 2x +1)=-2x^2-4x + 3

Option A)  (-x^2 - 2x + 4)-(x^2 + 2x +1)=-2x^2-4x + 3 is modeled by the algebra tiles
