I am getting only two correct answers ,wait I will post
OpenStudy (anonymous):
\[\huge \left| x^2-2x-8 \right|+\left| x^2+x+8 \right|=3\left| x+2 \right|\]
OpenStudy (anonymous):
So I cancelled mod(x-2)
and I get
\[\huge \left| x-4 \right|+\left| x-1 \right|=3\]
Parth (parthkohli):
Sorry, I'm back.
OpenStudy (anonymous):
By solving this , I get
answers as 1 and 4
but I don't get -2 which is also the answer

That's obviously because you cancelled \(|x+2|\) :P
OpenStudy (anonymous):
yeah , I know but you can't do without that
Parth (parthkohli):
I would instead take that common and then continue.
OpenStudy (anonymous):
\[ \Large \left| x+2 \right|(\left| x-4 \right|\left| x-1 \right|)=3\left| x+2 \right|\]
Parth (parthkohli):
Yeah, now take all of it on one side.

\[\Large \left| x+2 \right|(\left| x-4 \right|+x-1)-3\left| x+2 \right|=0\]
Parth (parthkohli):
Now take |x+2| common.
OpenStudy (anonymous):
oh I got it
Parth (parthkohli):
And you should put a mod on |x-1| btw.
OpenStudy (anonymous):
this equation tool sometimes is a pain , yeah
