Question

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

Explanation:

Step1: Count $x^2$ tiles

There are 9 blue $x^2$ tiles, so this term is $9x^2$.

Step2: Count $x$ tiles

There are 6 green $x$ tiles, so this term is $6x$.

Step3: Count constant tiles

There are 2 yellow 1 tiles, so this term is $2$.

Step4: Combine all terms

Add the three simplified terms together.
$9x^2 + 6x + 2$

Answer:

$9x^2 + 6x + 2$
