Question

e^(2x)+2e^x=24

Answer 1

what is e?

Answer 2

2 in(2)

Answer 3

Treat this as a quadratic in \(e^x\).
You can use a substitution: Let \(y = e^x\)
Then you have
\(y^2 + 2y - 24 = 0\)
Solve this quadratic for y.
Then substitute back \(e^x = y\) and solve for \(e^x\).
Finally, solve for x.
