If x =`5-2sqrt6` find `x-1/x`

If x = 5-2sqrt(6) find : x^(2)+ (1)/(x^(2))

If x=5-2sqrt(6)," find : "x^(2)+1/x^(2)

If x= 5 - 2 sqrt6 , find the value of : x^(2) +(1)/(x^(2))

If x=sqrt6+sqrt5 then find x^2+1/x^2-2

If x = sqrt(3)- sqrt(2) find the value of x+(1)/(x)

If x=1/(2-sqrt(3)), find the value of x^3-2x^2-7x+5

If x=1/(2-sqrt(3)), find the value of x^3-2x^2-7x+5

If x=1/(2-sqrt(3)), find the value of x^3-2x^2-7x+5

If x=2sqrt(3)+2sqrt(2) , find : (i) 1/x" (ii) "x+1/x" (iii) "(x+1/x)^(2)

If cos (pi/12) = (sqrt(2) + sqrt(6))/(4) , then all x in (0,pi/2) such that (sqrt(3)-1)/(sin x) + (sqrt(3)+1)/(cos x) = 4sqrt(2) , then find x.
