The polynomial below is a perfect square trinomial of the form a2 - 2ab + b2.

Option B.

Step-by-step explanation:

Given the polynomial:

 Observe that and are perfect squares. Then, you can rewrite the polynomial in this form:

You can identify that:

Then, we can check if

Since , the polynomial IS NOT a perfect square trinomial of the form

9 sandwiches per hour
