Question

prove that 0/0=2 using identity
$a {}^{2} - b {}^{2}$

Answer 1

Dear friend,
What you ask seems to be fallacy.

Let us prove that,

$\frac{0}{0} = 2$

$\frac{0}{0} = \frac{100 - 100}{100 - 100}$

$\frac{100 - 100}{100 - 100} = \frac{ {10}^{2} - {10}^{2} }{10(10 - 10)}$

$= \frac{(10 + 10)(10 - 10)}{10(10 - 10)}$

$\frac{10 + 10}{10} = \frac{20}{10} = 2$

.°. Hence proved

Hope it helps !!!
