\left[x _{1}\right] = \left[ - \sqrt[4]{\left( -1\right) }\right][x1]=[−4√(−1)]
\left[x _{1}\right] = \left[ \frac{sqrt3}{2}+\frac{ - \sqrt{\left( 4+sqrt3^{2}\right) }}{2}\right][x1]=[2sqrt3+2−√(4+sqrt32)]
\left[x _{1}\right] = \left[ \frac{sqrt3}{2}+\frac{ - \sqrt{\left( 4+sqrt3^{2}\right) }}{2}\right][x1]=[2sqrt3+2−√(4+sqrt32)]

Hi Mate!!!
Formula ( x² + 1 / x² ) = ( x - 1 / x )² +2
= ( x² + 1 / x² ) = ( √3 ) ² + 2
= ( x² + 1 / x² ) = 5
Have a nice time..

yes
why +4??
it is not + 4 but it. is +2
???
it is a formula......u can check it as well ......
do wana proof of it?
yes pls
ok
given formulla is. ( x² + 1 /x² ) = ( x - 1 / x )² + 2.......... Taking R.H.S. i,e. ( x - 1 / x )² + 2..........= x² + 1 / x² - 2 + 2 ......=. x² + 1 /x² that's equal to L.H.S. L.H.S = R.H.S hence proved..
we know that ( a - b )² = a²+ b² - 2ab
