Can you please isolate the variable r and simplify this equation (attached)? Don’t worry it’s not my homework. I tried Microsoft Mathematics to simplify but it can’t. I don’t have Mathematica so I can’t use that.

I need this equation for my project in Arduino. I can’t put it into my code.

Your help is appreciated. If this equation works I will share it here.

The first you can do is to Reduct to a common denominator.

Are you trying to solve r with given x,y,z? Do you know if it is solvable and how many roots r has? The original question that spawned this equation would answer some of the questions I/we have.
