`a^2-6a+1=0` then `a+!/a=`

If a^2-6a-1=0 then, find the value of a-1/a

If x^2- 6x + 1= 0 , then the value of (x^4+1/x^2) div (x^2+1) is यदि x^2- 6x + 1= 0 है, तो (x^4+1/x^2) div (x^2+1) का मान क्या होगा ?

If x^2-6x+1=0 , then the value of (x^4+1/x^2) div (x^2+1) is: अगर x^2-6x+1=0 , है तो (x^4+1/x^2) div (x^2+1) का मान है:

If 4x^2-6x+1=0 , then the value of 8x^3 +(8x^3)^-1 is: यदि 4x^2-6x+1=0 है, तो 8x^3 +(8x^3)^-1 का मान ज्ञात करें |

If alpha and beta are the roots of the quadratic equation x^(2)-6x+1=0, then the value of (alpha^(2))/(beta^(2))+(beta^(2))/(alpha^(2)) is

If m and n are roots of equations 2x^(2) - 6x +1=0 , then the value of m^(2) n+ mn ^(2) is:

IF alpha, beta are the roots of 9x^2+6x+1=0 then the equation with the roots 1// alpha , 1//beta is
