\(\displaystyle f(x)=A\left(((\frac{Q}{n-x}-\frac{R}{x})+(n-x))n\right)+Bnx+C((\frac{R}{x})n)\)

How can I find the value of x? I know that x can be between 1 to n-1. But how do I continue from there? I was thinking there must be a way to calculate it instead of trying a lot of possibilities. Like some derived equation for optimal value of x that made the whole formula sum the lowest possible.
