Solve the equation
To which David Butler added:
May I please add one thing, for the purposes of helping your student with future problems?
It might be very important to consider what happens for similar equations, such as THESE two:
\(e^{2x} + 9e^x + 18 = 0\)
\(e^{2x} + 9e^x - 10 = 0\)What other mathematical aspects of this caught your attention? What do you wonder about the situation?
