which polynomial is represented by the algebra tiles? 2x² - 4x - 6 2x² + 4x + 6 -2x² - 4x - 6 -2x² + 4x + 6

Explanation:

Step1: Count $x^{2}$ - tiles

There are 2 positive $x^{2}$ - tiles, so the $x^{2}$ - term is $2x^{2}$.

Step2: Count $x$ - tiles

There are 4 negative $x$ - tiles, so the $x$ - term is $-4x$.

Step3: Count unit - tiles

There are 6 negative unit - tiles, so the constant term is $-6$.

Answer:

$2x^{2}-4x - 6$
