Solutions are {-2,-1,0,1,2}

These are the values where the LHS equation and the line Y=-2 intersect

|C|!=A; therefore, A^2-3A+2+2=0
|C|!=1; C=0, 1, -1
|C|!=2; C=2, -2

What is the LHS?

LHS = Left hand side of the equation

I plotted the equation (|C|!)^2тАУ3(|C|!) and compared the graph with the line Y=-2 to find the common solutions

Yeah... sometimes, it is the only possible way to move ahead - to draw graphs. In my case, yet, it has been a simple quadratic equation...

Anyway, you are a strong matemetician; it is nice to deal with you.
