Answer is 16,, , do you want explanation,
x = √3-2
So, (x+1/x)²
={(√3-2)+1/(√3-2)}²
=[{(√3-2)²+1}/(√3-2)]²
=[{(√3)²-2√3.2+2²+1}/(√3-2)]²
={ -4(√3-2)/(√3-2)} ²
=(-4)²
= - 4×-4

x = √3-2
So, (x+1/x)²
={(√3-2)+1/(√3-2)}²
=[{(√3-2)²+1}/(√3-2)]²
=[{(√3)²-2√3.2+2²+1}/(√3-2)]²
={ -4(√3-2)/(√3-2)} ²
=(-4)²
= - 4×-4

(x + 1/x)²
= {(x²+1)/x}²
= { (3 - 2) +1}² / 3-2
= 2²/1
= 4
= {(x²+1)/x}²
= { (3 - 2) +1}² / 3-2
= 2²/1
= 4
