化简计算:2a-b-c/(a²-ab-ac+bc)+2b-c-a/(b²-ab-bc+ac)+2c-a-b/(c²-ac-bc+ab)化简计算:2a-b-c/(a
化简计算:2a-b-c/(a²-ab-ac+bc)+2b-c-a/(b²-ab-bc+ac)+2c-a-b/(c²-ac-bc+ab)
化简计算:2a-b-c/(a²-ab-ac+bc)+2b-c-a/(b²-ab-bc+ac)+2c-a-b/(c²-ac-bc+ab)
化简计算:2a-b-c/(a²-ab-ac+bc)+2b-c-a/(b²-ab-bc+ac)+2c-a-b/(c²-ac-bc+ab)
2a-b-c/(a²-ab-ac+bc)+2b-c-a/(b²-ab-bc+ac)+2c-a-b/(c²-ac-bc+ab)=(a-b+a-c)/(a-c)*(a-b)+(b-c+b-a)/(b-c)*(b-a)+(c-a+c-b)/(c-a)*(c-b)=0.亲
