Question: How do I write the equation of the phere passing through four points in a list of points?

I see from here http://www.mapleprimes.com/questions/220829-How-Do-I-Write-The-Equation-Of-The-Plane to write the equation of a sphere. I tried

But I couldn't get the result. How can get the result?
