Question

how to prove 2=1 ????​

Answer 1

Answer:

YES, ITS TRUE .

Step-by-step explanation:

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.

Answer 2

Answer:

Since a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = b. Combining the two terms on the left gives us: 2b = b. Since b appears on both sides, we can divide through by b to get: 2 = 1.
