Ifquad x+(1)/(x)=5," ind the Wrilue of "(x^(2)+1)/(x^(2))

If x+1/(x)=5 , then the value of x^(2)+1/(x^(2)) is:

If x-(1)/(x)=1 , then the value of (x^(4)-(1)/(x^(2)))/(3x^(2)+5x-3) is

If x+(1)/(x)=3 and x^(2)+(1)/(x^(3))=5 then the value of x^(3)+(1)/(x^(2)) is

If x+(1)/(x)=5 then what is the value of (x^(4)+(1)/(x^(2)))/(x^(2)-3x+1) ?

If x^(2)-5x+1=0 , then the value of (x^(4) + (1)/(x^(2))) div (x^(2)+1) is

If (x - (1)/(x)) = 5 then (x^(2) + (1)/(x^(2))) = ?

If x-1/x=5 , find the value x^(2)+1/(x^(2)) and x^(4)+1/(x^(4))

Let the equation x^(5) + x^(3) + x^(2) + 2 = 0 has roots x_(1), x_(2), x_(3), x_(4) and x_(5), then find the value of (x_(2)^(2) - 1)(x_(3)^(2) - 1)(x_(4)^(2) - 1)(x_(5)^(2) - 1).
