I'm just curious, I was looking at this question with a view to answer it, and suddenly the Community bot deleted it for abuse/spam. It didn't seem like either; it was just a regular question. Does anyone know why?
(Possible duplicate of Why is this answer “spam or offensive”?, but I don't have the tools personally to determine if it's the same cause.)
The question used to read, immediately before deletion and censorship,
How on earth do you graph $2 x^3 - 3 x^2 - 36 x + 7$ by hand?
I found this equation in a maths textbook that asked me to graph it, so to do so I tried to factor it. I used two different online calculators that couldn't do it either.
But I graphed it on Mathematica on turns out you can graph it?
