I've been solving this exercise and I came to a point when one function can get two different integrals:(adsbygoogle = window.adsbygoogle || []).push({});

Am I doing something wrong? Because both functions are the same, and the integrals (indefinite) are really different. This is a huge problem, because this is almost the final step of an exercise and when I exchange the current variable (x) with the previously defined function for it, the solution is VERY different.
