1.2, 1.4, and 1.5
I need big help on 1.4 and 1.5.
I think x = 5 for 1.2. I think 1.4 and 1.5 are factorable, but I don't know how to go about doing that. No examples in my textbook...

1.2 has no solution. There is no number that makes
============================================
1.4
Multiply by :
The first solution will be complex and the second real
or
===========================================
1.5: e^{5x}-2e^{3x}-3e^x=0
Divide by e^x (see 1.2 as to why e^x=0 is not a solution)
Set
