Question

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

Explanation:

Step1: Identify each tile's value

The red tile is $-x^2$, the green tile is $x$, and each yellow tile is $1$. There are 3 yellow tiles.

Step2: Combine the terms

Combine the constant terms (the 1s). So we have $-x^2 + x + 1 + 1 + 1$.

Step3: Simplify the constant terms

$1 + 1 + 1 = 3$, so the expression becomes $-x^2 + x + 3$.

Answer:

$-x^2 + x + 3$
