If `x^2+1/x^2` = 5 is given then find the value of (i) `x+1/x` (ii) ` x-1/x`

If x + (1)/(x) = 5 find the values of (i) x^(2) + (1)/(x^(2)) and (ii) x^(4) + (1)/(x^(4))

If (x - 1/x) = 4 , find the value of (i) (x^(2) - 1/(x^(2))) , (ii) (x^(4) + 1/(x^(4))).

If x^2+1/(x^2)=27 , find the values of each of the following: (i) x+1/x (ii) x-1/x

If x=1-i , find the value of x^2-2x+2

Given that x + (1//x) = 15 , then find the value of 5x ÷ (5x^(2) - 11 x + 5)

If (x-(1)/(x))=4 , find the value of (i)(x^(2)+(1)/(x^(2))), (ii)(x^(4)+(1)/(x^(4)))

Simplify : 3x (4x - 5) + 3 and find its value for (i) x = 3 , (ii) x = (1)/(2) (i) Put x =3, we have (ii) Put x = (1)/(2)

If x=sqrt(2)+1 , then find the values of the following : (i)(1)/(x)" "(ii)x+(1)/(x)" "(iii)x-(1)/(x)" "(iv)x^(2)+(1)/(x^(2))

If x=sqrt(2)+1 , then find the values of the following : (i)(1)/(x)" "(ii)x+(1)/(x)" "(iii)x-(1)/(x)" "(iv)x^(2)+(1)/(x^(2))
