Homework Statement
Solve ln(2x+1)=2-ln(x) for x.
Homework Equations
The Attempt at a Solution
e^(ln(2x+1)) = e^((2-ln(x))
2x + 1 = e^(2/x)
2x^2 + x = e^2
2x^2+x-e^2 = 0
At this point, I know you're supposed to use the quadratic equation. But, my problem is with how to treat e^2. Should I multiply it out in the discriminant where c = e^2? or just e?
Thanks for any help.
