      where are you from where algebra 2 is common sense? here it takes until like 8th or 9th grade to have enough math to learn this

    I think the point of task is not to just find K, but to prove it.

    Why does everyone take so much time and solve like a newbie writing down every tiny steps solving these literally 16 year old math problem?!

      Because his demographic needs an elaborate explanation and he is not leisure solving, they also consist of old people and enthusiastic children. Put the video in 2x if you find it slow.

    Wtf.
    K=2*root_6(1)
    Where I assume root_6 outputs a |C^6.
    Technically, it happens because I redefined/overloaded root_6. Roots output one number.
    There's 6 possibilities. Pick 1.
    2 and -2 are the reals.
    The after that you have 1/6th turns complex numbers.

      Yes, with complex number calculus everything boils down to a very simple solution.
