Q.Prove that 1=2.
(Explanation needed)​

Answer 1

Step-by-step explanation:

Let a = b

Multiply b on both sides

ab = b^2

Subtract a^2 on both sides

ab - a2 = b2 - a2

a ( b - a ) = ( b + a ) ( b - a )

Divide ( b- a )on both sides

a = b + a

Let a = b = 1

1 = 2

isn't there any way by which you can get your original I'd back ?

Answer 2

Answer:

We can also

write that,1–1=12−12

And this is true we all know that.

Now, applying formula[a2−b2=(a+b)(a−b)]

Then,1–1=(1+1)(1–1)

Till this all steps are correct.

Now, divide both side by (1–1) We get, 1=(1+1)∗1

Thus, 1 = 2
