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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
