(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

e^(2x+9) - 4e^x -5 = 0

2. Relevant equations

3. The attempt at a solution

I changed this into: e^(2x+9) =4e^x + 5

I took logarithm of both sides:

2x+9=ln(4e^x +5)

but i dont know what to do with the right hand side.

what will be the easiest way to solve this?

Thank you very much
