Question

Assume m = n
● Multiply by ‘m’ on both sides : m2 = mn
● Subtract n2 from both sides : m2 – n2 = mn – n2
● Factorize both sides : (m + n)(m – n) = n(m – n)
● Divide by (m – n) on both sides : (m + n) = n
● Since m = n , then 2n = n
● Divide by ‘n’ on both sides : 2 = 1
● Since 2 ≠ 1, what went wrong in the steps above?

Answer 1

Answer:

In forth step

Step-by-step explanation:

As we assumed that m=n,

m-n=0.

In the fourth step you divided both the sides with 0 basically which is not accepted in mathematics.

So your fourth step is where you made a mistake.
