Can someone please help to derive the variance equation in the equation attachment with respect to k. I am supposed to minimize portfolio variance with respect to return =k. I want the steps written out in variable form so that the answer is k= such and such variables in the end. I just want to see how someone does the calculus behind the equation step by step so that I can follow and then plug in the numbers myself. If I see how someone else solves it, I think i can apply it to problems later on. Thank you!

I am trying to learn this to solve question 1b on homework 1.
