Question 468194: I am struggling with the following problem:
2e^2x+5e^x-12=0
I know that we replace e^ with u, then use quadratic formula to solve. We get u=6 or u=-16.
Then, I guess we scratch the -16 because it's negative. From there I'm not sure how we are supposed to solve for x. I know that the answer is ln (3/2), but I'm not sure of the steps that go into solving for that and why the answer isn't ln3/2 or ln3/ln2, etc. Obviously you get here by setting 6=2e^2x, but I'm not sure why. Just need a brush-up on some rules here.
Thanks,
