I just started learning about polynomials, and I don't feel confident about my answers.. if an are wrong please correct me.

Zolita is correct! To make it easier to read I wrote them below, 100% guaranteed just took it!

1.B
2.A
3.B
4.C
5.D
6.B
7.A
8.D
9.A
10.B
11.B
12.Choose more than one, ABC

For Unit 3 Lesson 2 the answers for the practice are-

1B 2A 3B 4C 5D 6B 7A 8D 9A 10B 11B 12ABC

I just took the test and the answers are

1. B
2. A
3. B
4. C
5. D
6. B
7. A
8. D
9. A
10. B
11. B
12. A, B, C
So anyone that is getting confused with others answers... well... you don't have to be confused because I don't lie, I legit took the test, got number 3 wrong, I chose D instead of B, so I wanted you guys to not miss the question I got wrong. :)

100% with 11 as B, thanks for this!!

100% tysm!!

11 is B not C

The Multiplying and Factoring Polynomials Unit 4 Lesson 2 QuickCheck answers are the following :-)

1.)B
2.)C
3.)A
4.)D
5.)D

BLCKPNK FAN is still correct as of 2022, here are the answers:

1. 7x^2+28x
2. 8x^4 -28x^3+4x^2
3. 4
4. 9
5. 4
6. 3(3x-2)
7. t(t+8)
8. 2x(7x^2-x+4)
9. -60a^3 + 20a^2-70a
10. 17xy^3 (y+3x)
11. n(n+1)
12. n^2 + n is always an integer, n^2 + n is always an integer even when n is odd, n^2 + n is always an integer even when n is even.

Those who say that something is wrong with the answers I have given... well... YOU are wrong. I am a completely honest person, so don't worry about failing a PRACTICE, that has absolutely NO GRADE EFFECT AT ALL!

@Zolita is correct! & so is everyone else with the same answers!
