Question

Prove that 1=2 and write the proof

Answer 1

Answer:

Assume that we have two variables a and b, and that: a = b. Multiply both sides by a to get: a2 = ab. Subtract b2 from both sides to get: a2 - b2 = ab - b. This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b).

Answer 2

Answer:

1=2

Step-by-step explanation:

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
