Answer 2

[tex]4 x^{3} = 4 * ( \sqrt{3} +1) ^{3} /2 ^{3}
             = 4 * ( 3 \sqrt{3}+1+3 \sqrt{3}( \sqrt{3} +1))/8 [/tex]
             =[tex](3 \sqrt{3} +1+9+ \sqrt{3}) /2
             = (4 \sqrt{3} +10)/2 =2(2 \sqrt{3} +5)/2
             =2 \sqrt{3}+5 [/tex]
$2 x^{2}= 2( \sqrt{3} +1) ^{2} /2 ^{2}                   = (3+2 \sqrt{3} +1)/2                   =(4+2 \sqrt{3})/2$
                  = $2(2+ \sqrt{3})/2                   =2+ \sqrt{3}$
$-8x= -8( \sqrt{3} +1)/2=-4 \sqrt{3}-4$
on Subsituting these values,
[tex]= 2 \sqrt{3} +5+2+ \sqrt{3} -4 \sqrt{3} -4+7 = 10- \sqrt{3} [/tex]
Hope it helps
