c=13和c=127一个共同解都没有,何谈无穷多解?
a^2+a*b^2+a^2*b-a+1=13 {{a=-3,b=0},{a=-3,b=3},{a=1,b=-4},{a=1,b=3},{a=4,b=-4},{a=4,b=0}}
m^2+m*t^2+m^2*t-m+1=13^2 {{m=-8,t=2},{m=-8,t=6},{m=3,t=-9},{m=3,t=6},{m=7,t=-9},{m=7,t=2}}
a^2+a*b^2+a^2*b-a+1=127 {{a=-7,b=2},{a=-7,b=5},{a=3,b=-8},{a=3,b=5},{a=6,b=-8},{a=6,b=2}}
m^2+m*t^2+m^2*t-m+1=127^2 {{m=-48,t=7},{m=-48,t=41},{m=-42,t=11},{m=-42,t=31},{m=8,t=-49},{m=8,t=41},{m=12,t=-43},{m=12,t=31},{m=32,t=-43},{m=32,t=11},{m=42,t=-49},{m=42,t=7}}
