Question

(2x+1)/x < 0

Answer 1

This is what I've done so far.

=> (2x+1) > 0
=> x > -1/2

Not sure if that's right.

Answer 2

It should actually be -1/2 < x < 0.

I can't figure out how to get the 0. It is correct logically.

Answer 3

For this to be defined, will never be equal to 0.
This shows that x is between (-1/2,0)
I hope this answer your question

Answer 4

Thanks!
Do you have a solution that can be written using mathematical symbols (i.e not a graph)?

Answer 5

I think I figured it out. I used a sign table.

Answer 6
