Question

what expression does this set of algebra tiles represent?
-x² -x² 1 1 1
combine like terms. for example, write 3 instead of 1 + 1 + 1.

Explanation:

Step1: Identify $x^2$ terms

There are 2 tiles of $-x^2$, so sum is $-x^2 + (-x^2) = -2x^2$

Step2: Identify constant terms

There are 3 tiles of $1$, so sum is $1 + 1 + 1 = 3$

Step3: Combine all terms

Add the results from Step1 and Step2.

Answer:

$-2x^2 + 3$
