Question

how can you prove 2=1 (by using infinity)

Answer 1

2 * infinity = 1* infinity

==> 2=1

But you cannot do this as infinity is not a number its a concept!

Hope it helps

Answer 2

Answer:

$\huge\underline{ \underline{ \blue{your \: \: answer}}}$

Step-by-step explanation:

$\sf\red{ = > a = b - - - - (1)} \\ \sf\red{ = {a}^{2} = ab} \\ \sf\red{ = > {a}^{2} - {b }^{2} = ab - {b}^{2} } \\ \sf\red{ = > (a + b)(a - b) = b(a - b)} \\ \sf\red{ = > a + b = b} \\ \sf\red{ = > a + a = a} \\ \sf\red{ = > 2a = a} \\ \sf\red{ = >2 = \frac{a}{a} } \\ \sf\red{ = > 2 = 1} \\ or \\ \sf\purple{1 - 1 = {1}^{2} - {1}^{2} } \\ \sf\purple{ = > 1 - 1 = (1 + 1)(1 - 1)} \\ \sf\purple{ = > \frac{(1 - 1)}{(1 - 1)} = \frac{(1 + 1)(1 - 1)}{1 - 1} } \\ \sf\purple{ = > 1 = 1 + 1} \\ \sf\purple{ = > 1 = 2} \\ \large\boxed{ \fcolorbox{red}{purple}{hope \: it \: help \: you}}$
