怎樣證實這題1+1=2係錯?
發問:
假設A=B A^2=AB A^2 -B^2= AB -B^2 (A -B) (A+B)=B(A -B) A+B=B 2B=B 1+1=1????????
最佳解答:
你在一開始的假始已出了問題 假設A=B A^2=AB A^2 -B^2= AB -B^2 (A -B) (A+B)=B(A -B)
其他解答:
the process from third process to fourth process is wrong. because if you both side diveded by A-B, it means that diveded by 0, it is wrong.
