Is this your expression?

Answer 4

no...

Answer 5

parenthesis means its all one expression inside

Answer 6

then you dont have the parenthisis on the correct place. Cant help you again

Answer 7

so if i say (1/x-4) it looks like this

Answer 8

if i meant what you said it would read (1/x)+4

Answer 9

why dont you just type like this like a normal person:

1/(x-4) - 5/(x+2) = 6/(x^2+x-6)

Answer 10

you know what the problem is now can you help?

Answer 11

im on it. just a sec

Answer 12

a) x=-3 x=-2 x=2 x= 4
b) http://i.imgur.com/16Ote.png

Answer 13

the books given answers were a) -2,4 and b) 0

Answer 14

i understand the -2,4 but not the 0

Answer 15

in which grade are you?

Answer 16

sophomore college

Answer 17

do you already know what imaginary numbers are?

Answer 18

yes

Answer 19

hmm.. your answers are for the left side of the equation, right? cause if X = -3 or x= 2 on the right side, the dominator is also 0

Answer 20

oh sorry the book answer is no solution, not zero

Answer 21

no -3 works for the right side

Answer 22

9-6-8 isnt 0

Answer 23

9+6-8*

Answer 24

(-3)^2 -3-6
9 -9 = 0

-3 works

Answer 25

i fear ive wasted your time, i accidentally entered the wrong numbers for the last 3 numbers on the right side looking at another problem

Answer 26

the right side is actualy 6/(x^2-2x-8)

Answer 27

sorry

Answer 28

ohhh so that only changes.... EVERYTHING

a) x= 4 x= -2
b) no solution

Answer 29

hahahha

Answer 30
