SOLUTION: e^2x-5(e^x)+6=0 if you have a similar question with a coefficient greater than 1 it would be great if I had some help on it cause today is my final exam, and thankyou.

You can put this solution on YOUR website!
e^2x-5(e^x)+6=0
Sub u for e^x
---
u^2 - 5u + 6 = 0
(u - 2)*(u - 3) = 0
u = 2, 3
---
e^x = 2, 3
x = ln(2)
x = ln(3)
