2=1? Solution.

Updated: Apr 16, 2023

6th line from bottom:

Cancel (a-b).

Remember a = b so

a-b = 0

You can not divide by 0!

2 = 1

How can 2 = 1 ? First, recall (a + b)(a – b) = a2 – ab + ab – b2 = a2 – b2 Then let’s go: a = b a2 = ab a2 – b2 = ab – b2 (a + b)(a – b) = b(a – b) Cancel (a – b) a + b = b Remember a = b so b + b = b
