Question

$x {}^{2} - x {}^{2} =x {}^{2} - x {}^{2} \\ x(x - x) = (x + x)(x - x) \\ x = x + x \\ x = 2x \\ 1 = 2$
Am is right right or wrong?
how is this possible?​
Explain it

Answer 1

The solution for x becomes not define on first step as ${x}^{2} - {x}^{2} = 0$ only..

${x}^{2} - {x}^{2} = {x}^{2} - {x}^{2} \\ \\ 0 = 0$

So let's divide 0÷0 =>

$dividing \: \: both \: \: sides \: \: by \: 0 \implies \\ \\ \frac{0}{0} = \frac{0}{0} \\ \\ By \: limits \: We \: can \: prove \frac{0}{0} = any \: no. \\ \\ any \: no = any \: no$

Using the following equation you can prove any no = any no
