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 \( x^2 \) terms

There are 4 + 4 + 2 = 10 \( x^2 \) tiles. So the \( x^2 \) term is \( 10x^2 \).

Step2: Count \( -x \) terms

There are 6 \( -x \) tiles. So the \( -x \) term is \( -6x \).

Step3: Count \( -1 \) terms

There are 3 + 2 + 2 = 7 \( -1 \) tiles. So the constant term is \( -7 \).

Step4: Combine like terms

Combine the terms: \( 10x^2 - 6x - 7 \).

Answer:

\( 10x^2 - 6x - 7 \)
