Java polynomial root search

I am new to Java and have created a Polynomial Root Finder with a GUI. One of the problems I'm currently running into and don't quite understand is the value that comes from perfect squares like (x + 5) ^ 2.

int y = 0;
    for(int x = -100000; x < 100000; x++) {
        int math = (A * (x * x)) + (B * x) + C;
        if(math == 0) {
            Zeros[y] = x;
            y++;
        }
    }

      

        
        
        
      

    

Now for some reason Zeros [0] returns -65541 and I'm not sure why. Now if I make x bounds from -10000 to 10000 the problem goes away and shows the correct roots. I'm just asking why -65541 gets as root.

Here is a photo of my problem.
