Question

prove 1=0 or prove that 2=0

​

Answer 1

Answer:

PROVED 2=0

Step-by-step explanation:

Let x = 1.

Square both sides: x2 = 1

Subtract 1 from both sides: x2 – 1= 0

Factor: (x+1)(x-1) = 0

Divide both sides by (x-1): x+1 = 0

Substitute the value of x: 1 + 1 = 0

Conclusion: 2 = 0.

Answer 2

The difficulty with both "proofs" is a division by zero error.

In the proof that 1 = 0, you divide by zero when you go from step 5 to step 6.

In the proof that 0 = 2, you divide by zero when you go from step 8 to step 9.
