ok im going to guess u meant:

instead of
x.2/(2.x+1)=1
.

multiply by a number that will eliminate the denominators accross the equation
in this case the number is
use cross cancelation when distributing
distribute the x
put in quadratic formula

Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=21 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 1.79128784747792, -2.79128784747792. Here's your graph:
