Answer 8

The question \[\frac{ 9-r^2 }{ r^2-2r-3 }\times \frac{ 3-4r^2 }{ r^2+4r+3 }\] and sweet i could of really used that a minute ago.

Answer 9

and my answer \[\frac{ 4(r-1) }{ (r+1) }\]

Answer 10

wait, i think you are right, just had a typo in the question

Answer 11

you had a 2nd one?

Answer 12

ohh sorry i was trying to figure out the calculator you gave me. and was i right?

Answer 14

and my last question. i just realized that it wasnt one of the answers so can you help me figure it out?

Answer 15

@dumbcow

Answer 16

sure

Answer 17

\[\frac{ 3c^2 }{ c^2-2c }\times \frac{ c^2-4 }{ c }\]

Answer 18

this is what i got so far from factoring it\[\frac{ ? }{ c(c-2) }\times \frac{ (c-2)(c+2 }{ c }\]

Answer 19

I dont know about the top of the first one

Answer 20

it would just stay "3c^2"

Answer 21

multiply the c's on bottom to get ---> c^2 (c-2)

Answer 22

to get c^2-2c?

Answer 23

no that will just get you back where you started

the "c" on bottom in other fraction

Answer 24

oh okay

Answer 25

\[\frac{3c^2 (c-2)(c+2)}{c^2 (c-2)}\]

Answer 26

okay and would the (c-2) cancel out on top and bottom?

Answer 27

yes as well as the c^2

Answer 28

so my answer would be 3(c+2)

Answer 29

yes

Answer 30

sweet thank you! thats all i have.

Answer 31
