Question

if x is equals to 5 minus 2 root 6 then find the value of x minus one upon x

Answer 1

Answer:

Step-by-step explanation:

$x = 5-2\sqrt{6} \\ \frac{x-1}{x} = ?$;

Putting the value of x in this eq. we get = $\frac{4-2\sqrt{6} }{5-2\sqrt{6} }$;

Now doing rationalization;

$\frac{(4-2\sqrt{6} )(5+2\sqrt{6} )}{(5-2\sqrt{6} )(5+2\sqrt{6} )}$;

By solving this;

20 - 4*6 - 10$\sqrt{6}$ + 8$\sqrt{6}$;

-4 - 2$\sqrt{6}$
