I have a difference of opinion with 2 calculation engines.(adsbygoogle = window.adsbygoogle || []).push({});

equation to solve is;

d/dx (a(x^2 +y)

Wolframalpha of course is a very trusted source but I also use symbolab.

Here is a screenshot of the differential I want from both sites and associated answers.

. . . and the wolfram solution

could anyone please confirm which is correct.

Personally I like the symbolab solution.
