Question

4-c/2c-8
Please show all work, and state any excuded values

Answer 1

\[4 - c = -(c - 4)\]Right?

Answer 2

idk..

Answer 3

is it like this
\[\Large \frac{ 4-c }{ 2c }-8\]
??

Answer 4

No like this @kausarsalley \[\frac{ 4-c }{ 2c-8 }\]

Answer 5

factor out a 2 at the bottom...so you'd have

(4- c)/2(c - 4)

Answer 6

so like \[\frac{ 4c }{ 2(c-4) }\]

Answer 7

now you have to find the zeroes?

Answer 8

Hmm?

Answer 9

no it would look like \[\large \frac{4-c}{2(c-4)}\]

Answer 10

ooh oops i forgot the minus

Answer 11

ok now what?

Answer 12

for excluded values, equal the numerator and denominator to 0 and solve for c.

Answer 13

Ok factoring, right?

Answer 14

\[\dfrac{4 - c}{2(c - 4)}\]can be simplified

Answer 15

Oh yea...distribute

Answer 16

so
\[\frac{ 4-c }{ 2c-8 }\]

Answer 17

?

Answer 18

Uh no.\[\dfrac{4 - c}{2(c -4)} = \dfrac{-(c - 4)}{2(c - 4)}\]

Answer 19

well the negative......

Answer 20

Ok..why don't you distribute..?

Answer 21

Why would we distribute? That just gets us back to the original question lol

Answer 22

oh yea

Answer 23

Because like he showed above, those can cancel out, leaving you with -1 ontop.

Answer 24

so what we are doing is un-distributing...kinda?

Answer 25

we've already un-distributed haha

Answer 26

we're....re-simplifying.

Answer 27

We're factorizing.

Answer 28

ok

Answer 29

so after -(c-4)/2(c-4) what would it be?

Answer 30

what does (c-4)/(c-4) = ?

Answer 31

they cancel out

Answer 32

so what's left over?

Answer 33

so you are left with 2 does not equal -1?

Answer 34

?

Answer 35

:D was i right?

Answer 36

@Jhannybean

Answer 37

\[\large -\frac{\cancel{(c-4)}}{2\cancel{(c-4)}}=-\frac{1}{2}\]

Answer 38

Ohhh that makes so much sense :D I love you (lol like a sister )

Answer 39

ok what is theexcuded value

Answer 40

is it c doesnt equal -1/2? @jhannybean

Answer 41

\[c \neq-\frac{ 1 }{ }\]

Answer 42

\[c \neq-\frac{ 1 }{ 2 }\]***

Answer 43

?

Answer 44

@jh

Answer 45

@Jhannybean ***

Answer 46

Hm... not too sure.

Answer 47

actually its \[c \neq4\]
