Answer:
Option D is correct
Step-by-step explanation:
The original polynomial is:
–2x2 + 2 + 5x3 – 5x
Arranging in decreasing power of x:
Factoring the given polynomial by grouping:
Now, (x^2-1) can be further solved using formula:
(a^2-b^2)=(a-b)(a+b)
Solving:
So, represents the factors of
Hence Option D is correct.

Multiply 1.04 by the amount of the cost, to get your answer.
But, to make this easier, and to not go through more work, lets round your money amount to $250
Now, all you have to do is multiply.
$250 · 1.04 ≈ $260
So, your answer for $250 with 4% (1.04) percent sales tax would be a grand total of:
$260

-Hope this helped :)
250*1.04=260 or 259.9975 if you want to be technical
