Answer 1

D, C, A, C, A

Answer 2

which ones are those?

Answer 3

Those are the first five. Sorry it's confusing to keep switching tabs.

Answer 4

its fine, lol i'm doing the same thing. hahaha

Answer 5

So, does that mean the rest are correct?

Answer 7

gal maybe lol idk

Answer 8

okay, sorry. lol :) and i'm a girl :)

Answer 9

lol

Answer 10

my name is Renee sooo... yeah hahaha

Answer 11

1. The GCF of 12 and 36 is 12. It multiplies into both 12 (12*1) and 36 (12*3) with no remainder.
2. The GCF of x^4 and x^3 is x^3.
3. 3x - 2 = 3(x - 4)
4. 4x^2 + 16x = 4x(x+4)
5. 2x^2 + 4x - 2 = 2(x^2 + 2x - 1)
6. 10x^5 + 4x^4 + 8x^3 = 2x(5x^4 + 2x^3 + 4x^2)
7. 5a^2 + b = Prime.
8. 2x^3y^4 - 8x^2y^3 + 6xy^2 = 2xy^2(x^2y^2 - 4xy + 3)
9. -3x^2 + 6x - 9 = -3(x^2 - 2x + 3)
10. -2x^3 + 6x^2 = -2x^2(x-3)

Answer 12

The rest:
C, A
I'd say 8 is C. 2xy^2(x^2y^2 − 4xy + 3), but those parenthesis can be factored further.

Answer 13

9) A
10) C

Answer 14

wow, thanks for explaining that :)

Answer 15

When you are factoring, look it the highest exponent of x in common with both terms, so you can pull that out of the parenthesis.

Answer 16

hey, bahrom7893, I think you did 6 wrong... I still think its C. but thanks for your help, you as well ten.

Answer 17

6? Let me check again..

Answer 18

6. Factor completely: 10x^5 + 4x^4 + 8x^3

A. Prime
B. 2(5x^5 + 2x^4 + 4x^3)
C. 2x^3(5x^2 + 2x + 4)
D. 2x(5x^4 + 2x^3 + 4x^2)

Yes you're right, it should be 2x^3(5x^2 + 2x +4)

Answer 19

What did I say for 6? I did say C

Answer 20

Thanks, I thought so, that one tricked me the first time I looked at it, but when I went back to check it, I made me change my answer! Just goes to show how important it is to check your answers. :D

Answer 21

you said D.

Answer 22

Anyway, thanks for all of your guys help, I really do appreciate it :)

Answer 23

I read his/her answer as being C for 6 ;)
