Question

My proof of 1=2.......

Answer 1

Assume that we have two variables
a and b, and that: a = b
Multiply both sides by a to get: a 2 =
ab
Subtract b 2 from both sides to get:
a 2 - b 2 = ab - b 2
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 ). If
you're not sure how FOIL or
factoring works, don't worry—you
can check that this all works by
multiplying everything out to see
that it matches. The end result is
that our equation has become: ( 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: 2 b = b
Since b appears on both sides, we
can divide through by b to get: 2 = 1

THATS MY ANSWER
