Question

x is 1 by 3 plus 2 root 2 find value of xminas 1 by x is​

Answer 1

HEYA!!

Answer:

$x = \frac{1}{3 + 2 \sqrt{2} }$

we need to find

$\frac{x - 1}{x}$

so on putting the value of x in above equation

we get

$\frac{ \frac{1}{3 + 2 \sqrt{2} } - 1 }{ \frac{1}{3 + 2 \sqrt{2} } }$

$\frac{ \frac{1 - 3 + 2 \sqrt{2} }{3 + 2 \sqrt{2} } }{ \frac{1}{3 + 2 \sqrt{2} } }$

$\frac{1 - 3 + 2 \sqrt{2} }{3 + 2 \sqrt{2} } \times \frac{3 + 2 \sqrt{2} }{1}$

$\frac{ - 2 + 2 \sqrt{2} }{1}$

$= > - 2(1 + \sqrt{2} ) \\ will \: be \: your \: answer$
