Question

Prove 1=2. Give step by step explanation. ​

Answer 1

Answer:

The Proof that 2 = 1

1) a = b 1) Given.

2) a2 = ab 2) Multiply both sides by a.

3) a2-b2 = ab-b2 3) Subtract b2 from both sides.

4) (a+b)(a-b) = b(a-b) 4) Factor both sides.

5) (a+b) = b 5) Divide both sides by (a-b)

6) a+a = a 6) Substitute a for b.

7) 2a = a 7) Addition.

8) 2 = 1 8) Divide both sides by a.
