Partial differential - difference of opinion

Click For Summary
The discussion revolves around a disagreement regarding the differentiation of the equation d/dx (a(x^2 + y)) using two calculation engines: WolframAlpha and Symbolab. The user highlights that WolframAlpha interprets 'a' as a function of 'x^2 + y', while Symbolab provides a solution that aligns more with their expectations. The user admits to a potential oversight in not clearly indicating that 'a' is a constant multiplied by the expression. They seek confirmation on which solution is correct, emphasizing the importance of clarity in mathematical notation. The conversation underscores the significance of precise expression in calculus to avoid misinterpretations.

I have a difference of opinion with 2 calculation engines.

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.

The point is, wolfram assumed you mean a is a function and its argument is x^2+y. You should have written a*(x^2+y).
 
oops sorry. Just me being lazy
