Hi All,

Just trying to solve:

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

I try:

2x+1>=2x-1

0>=-2 (not the answer I want)

I tried:

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

4x^2-1>=4x^2-4x+1

-2>=-4x

x>=1/2 (can't be this, it is undefined)

I also tried:

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

4x^2+4x+1>=4x^2-1

4x+1>=-1

4x>=-2

x>=-1/2 (but this answer doesnt work with the inequality...0>=1??)

Not sure what to do now...by looking at the graph I think x>=1/2...but like i said, this is undefined...
