1<(3x^(2)-7x+8)/(x^(2)+1)<2

If x = sqrt7 + sqrt6 , then find the simpliest value of (a) x - (1)/(x) , (b) x + (1)/(x) , (c) x^(2) + (1)/(x^(2)) , (d) x^(3) + (1)/(x^(3))

(7x^(3)+3x^(2)-x+1)/(x+1)=(ax^(2)+bx+c)-(2)/(x+1)

Let the root of equation (3x^(3)-x^(2)+x-1)/(3x^(3)-x^(2)-x+1)=(4x^(3)+7x^(2)+x+1)/(4x^(3)+7x^(2)-x-1) be x_(1),x_(2),x_(3) then the value of x_(1)+x_(2)+x_(3) is

If (x+(1)/(x))=3, then (x^(2)+(1)/(x^(2)))=?( a )7( b) 9(c)10(d)27

If (x^(2) - x - 1)^(x^(2) - 7x + 12) = 1 then

If (x^(2) - x - 1)^(x^(2) - 7x + 12) = 1 then
