I have the value of x (used my graphing calculator), but I need to be able to show the work. Can anyone give me an idea of what to do here?
1. This obviously has two real roots if it has any
2. Numericaly they are 1.04573 and 6.42411
3. This may have a closed form solution in terms of the Lambert W function but I will have to look into that.
4. The inverse symbolic calculator does not recognise either of these (when extended to 11 significant digits).
