Hopefully, this kind of question is ok, have seen a couple of other WA-queries that hasn't been downvoted. Apologies if not.

I want to minimize say $f(x)=ax^2+bx+c$. Wolfram Alpha gives me an answer for different intervals of $a$ which makes sense. However, Is there a way to explicitly specify $a>0, b>0, c>0$?

Yes, you can simply include those constraints: minimize ax^2+bx+c, a>0, b>0, c>0

Alternatively, you can complete the square and observe the extreme value occurs when $x=-\frac b{2a}$: complete the square ax^2+bx+c
