e^4x + 6e^2x - 27 = 0

I understand how factoring it should work by replacing the 'e's but I'm not sure how to do it

retireed · Answer

I got two different answers, by solving two different ways.

By graphing I got    x = 0.549306   I trust this more than my math with exponents.

By algebra I got x = 0.42288
