Answer 2

AnswEr:-

Assume that we have two variables a and b, and that: a = b

Multiply both sides by a ,

⇒  a² = ab

Subtract b² from both sides,

⇒ a²- b² = ab - b²

Factor the left side to get (a + b)(a - b) .

Factor out b from the right side to get b(a - b).

⇒(a + b)(a - b) = b(a - b)

Since (a - b) appears on both sides, we can cancel it to get: a + b = b

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

Hence proved .
