you didn't do anything wrong. your answer is correct. notice that the -2 from (e^x - 2) can be combined with the constant C to produce another arbitrary constant. once you do that, your answer will look just like the other answer.
Am i doing this problem wrong?
Evaluate the integral
<-- that is e^(2x)
i expanded the problem to:
i picked u to be e^x - 2
rewrite to:
multiply all out to
integrate and get:
but the answer says its:
what did i do wrong?
