(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given y = x^2 + 6 / x find x if dy/dx equals 0 zero

2. Relevant equations

dy/dx = v du/dx - u dv/dx / v^2

3. The attempt at a solution

I have got as far as dy/dx = x^2 - 6 / x^2

However then zero must equal Sqrt 6, which 2.44.... - can someone please confirm.

Many thanks.
