Question

what expression does this set of algebra tiles represent?
image of algebra tiles: two x² tiles, six x tiles, two x tiles, and ten -1 tiles (arranged as four in first row, three in second, three in third)
combine like terms. for example, write 3 instead of 1 + 1 + 1.

Explanation:

Step1: Count $x^2$ tiles

There are 2 blue $x^2$ tiles, so we get $2x^2$.

Step2: Count $x$ tiles

There are $6 + 2 = 8$ green $x$ tiles, so we get $8x$.

Step3: Count constant (-1) tiles

There are $4 + 3 + 3 = 10$ red -1 tiles, so we get $-10$.

Step4: Combine like terms

Add the terms from the previous steps together.
$2x^2 + 8x - 10$

Answer:

$2x^2 + 8x - 10$
