Question

Pls!! Which sum or difference is modeled by the algebra tiles?

Answer 1

Answer:

Option C.

Step-by-step explanation:

Basically, to solve this problem, we just have to find the sum or difference that results in $2x^{2}+2x+2$

Option A:

$(x^{2}+4x-2)+(x^{2}-2x-4)=2x^{2}+2x-6$

Option B:

$(x^{2}+4x-2)+(x^{2}+2x+4)=2x^{2}+6x+2$

Option C:

$(x^{2}+4x-2)-(-x^{2}+2x-4)=x^{2}+4x-2+x^{2}-2x+4=2x^{2}+2x+2$

Therefore, option C is the expression which models the algebra tiles.
