Step-by-step explanation:
It comes from integrating by parts twice. Let
Recall the IBP formula,
Let
Then
Apply IBP once more, with
Notice that the ∫ v du term contains the original integral, so that
Expanding the left side gives
which gives two solutions,
and
. But if
, then
, but this number isn't real, so
is an extraneous solution. Meanwhile if
, you get
, so this solution is correct.
"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.
