Question

Someone please help me with this absolute value equation Please

Answer 1

wait @satellite73

Answer 2

\[\huge \left| x ^{2}-3x-4 \right|=9-\left| x ^{2}-1 \right|\]

Answer 3

wow!!

Answer 4

just give me a hint i want to do the work

Answer 5

i thought it was going to be an easy one
i would work in cases

Answer 6

i don't ask easy questions :P

Answer 7

cases like how

Answer 8

first off lets change the form a bit

Answer 9

COol

Answer 10

I think bringing the mod to L.H.S

Answer 11

\[|x+1||x-4|+|x+1||x-1|=9\]

Answer 12

yeah that and also factor

Answer 13

uhhm yup!

Answer 14

factor out the common factor of \(|x+1|\) then get rid of it

Answer 15

after this

Answer 16

okay wia t

Answer 17

i am not getting u after factoring

Answer 18

\[|x+1||x-4|+|x+1||x-1|=9\]
\[|x+1|(|x-4|+|x-1|)=9\] oh no don't get rid of it, sorry it is an equation not an inequality

Answer 19

yeah i did that part

Answer 20

Then we take critical points?

Answer 21

like -1 , 4 , 1

Answer 22

what i said "work in cases" i mean for example if \(x>4\) then this is the same as
\[(x+1)((x-4)+(x-1))=9\]

Answer 23

yes exactly

Answer 24

cool i will work it out , i will notify you when i am done just 3 minutes

Answer 25

i have to run, but i am sure you will get it
