If `x^2-x-1=0,` then the value of `x^3-2x+1` is

If x^2 - 3x +1=0, then the value of x +1/x is

If x^2-3x-1=0 , then the value of (x^2+ 8x-1)(x^3+x^(-1))^-1 is: यदि x^2-3x-1=0 है, तो (x^2+ 8x-1)(x^3+x^(-1))^-1 का मान क्या होगा ?

If x^2 - 3x + 1 = 0 , then the value of (x^6 + x^4 + x^2 + 1)/(x^3) will be

If x^2+1/x^2=7, then the value of x^3+1/x^3 Where x>0 is equal to:

If x^(2)-3x+1=0 , then one of the values of (x^(2)-8x-1)/(x^(3)+1//x) is :
