Solve an integro differential equation

Posted 4 years ago

Consider the following code:

In[1]
    eqn = f2[w] == A + (\[Lambda]/k*\!\(
    \*SubsuperscriptBox[\(\[Integral]\), \(Q\), \(w\)]\(
    \*SuperscriptBox[\(e\), \(\(-\[Mu]\)*\((t - w)\)\)]*
            f2[t] \[DifferentialD]t\)\));
    sol = DSolveValue[eqn, f2[w], w]

But I got this answer

Out[2]
A + (\[Lambda] \!\(
\*SubsuperscriptBox[\(\[Integral]\), \(Q\), \(w\)]\(\(
\*SuperscriptBox[\(e\), \(\((\(-t\) + w)\)\ \[Mu]\)]\ f2[
      t]\) \[DifferentialD]t\)\))/k
