Which statement justifies that x2 + 3x − 1 multiplied by 2x2 − 2x + 1 obeys the closure property of multiplication?
olya-2409 [2.1K]
(x² + 3x - 1)(2x² - 2x + 1)

x²(2x² - 2x + 1) + 3x(2x² -2x + 1) -1(2x² - 2x + 1)
2x^4 - 2x³ + x² + 6x³ - 6x² + 3x - 2x² + 2x - 1
2x^4 - 2x³ + 6x³ + x² - 6x² - 2x² + 3x + 2x - 1
2x^4 + 4x³ - 7x² + 5x - 1

<span>(D)The result 2x4 + 4x3 − 7x2 + 5x − 1 is a polynomial.</span>

Perform the operation.<br> (-x^2 – 1) – (-2x^2 – 4)
ivolga24 [154]

Answer:

Okay!

Step-by-step explanation:

I have simplified the operation, and I got x^2 + 3.

If you wanted me to evaluate, the answer is still  x^2 + 3.

If you wanted me to subtract then the answer is again,  x^2 + 3.

Basically the answer is  x^2 + 3.

Have a good day!
