Answer 4

or perhaps I should say greatest common factor

Answer 5

5

Answer 6

right?

Answer 7

Yup, so lets divide both of those groups by 5

Answer 8

5(2a^3b^4c-3a^3bc^2)

good so far?

Answer 10

so are you finished with the first question now? I didn't give you the full answer

Answer 12

oo wait wrong problem

Answer 13

oo nvrmind it isn't the wrong one

Answer 14

yeah it looks good to me

Answer 15

ok thanks i think i am good

Answer 16

is this right?
-11x^5y+22xy= -11xy(x^4+2)

Answer 17

remember that you can always check your work by reversing what you did (so multiplying -11xy by (x^4+2)

Answer 18

oo ok

Answer 19

but i am confused on when the gcf is a negative or positive

Answer 20

Well two negatives make a positive and two positives make a positive. If the signs are different, it will be negative. What part are you having trouble with?

Answer 21

but what about a problem like this... 8x^7y^4z+12xyz-16y^2z^3....... theres three different numbers

Answer 22

Find the gcf for all three groups, and then divide each group by the gcf. It is sometimes easier to understand if you put the gcf under each group of terms, because then you can concentrate on each one separately.

Answer 23

would it be 4 or -4?

Answer 24

honestly it doesn't really matter. usually you want the first term in the brackets to be positive. So -3(x+4) looks a lot better than 3(-x-4)

Answer 25

ok

Answer 26

Thanks for the medal. Let me know if you have anymore questions.

Answer 27

ok thanks

Answer 28

ok I tried to do....4x^2-5x-6 and got (4x+3) (x-2) but my teacher got (4x+3) (x-2x)... i don' t get why there is the x on right next to the 2

Answer 29

ok I will try

Answer 30

Your answer is correct. Remember that you can multiply out your answer to see if you get the stuff you were originally given. This is a great way to tell if you are right or not.
