Thank you for all the inputs.

So after differentiating I got this:


This is what I should solve to 0

I looked into this Newton-Raphson method, its really interesting and could provide a really good approximation of root this function in a couple of steps but I should differentiate this again, and it makes it way too complicated.
only the first part looked like this:



wouldn’t be more efficient just increasing/decreasing the value of x in a cycle In the original equation until the value of y won’t get any smaller?
Whole numbers are fine for me, I don’t need any decimals.



doen't that equate out to 100?

16+22+25+22+11+4=100

NO, it does not
you are missing the absolute value

And remember that Newton-Raphson can only be applied to a differentiable function, and well - this one is not differentiable.
