SUMMARY

The equation (e^(2x)) - (3e^x) + 2 = 0 can be simplified by substituting w = e^x, transforming it into w^2 - 3w + 2 = 0. This quadratic equation can be factored into (w - 1)(w - 2) = 0, yielding solutions w = 1 and w = 2. Consequently, solving for x gives x = ln(1) = 0 and x = ln(2), providing the final solutions for the original equation.

Homework Statement


Solve for x.
e2x-3ex+2=0


The Attempt at a Solution


e2x-3ex+2=0
-e2x+3ex=2
ex(3-ex)=2
lnex(3-ex)=ln2
x(3-ex)=ln2

..not very sure where to go here. Any direction would be appreciated! Thanks

I wouldn't do what you wrote above. Start with this: let w = ex. Then rewrite the equation in terms of w. Does the equation look familiar now?
