Question

What must be added ti 1/x to make it equal to x​

Answer 1

Answer:

Thus, we added xx2−1 to x1 to make it equal to x.

Answer 2

Answer:

Let the number added be a

$∴ \frac{1}{x} + a = x$

$\implies \: a = x - \frac{1}{x}$

$\implies \: a = \frac{ {x}^{2} - 1} {x}$

Therefore,

$\implies \: a = \frac{ {x}^{2} - 1} {x}$

is added to 1/x to make x
