" 3."(3)/(4)x^(2)-x-1=0

one root of x^(3)3x^(2)+4x-1=0 lies between

((2-x^(2))(x-3)^(3))/((x+1)(x^(2)-3x-4))>=0

The equation x^(4) -2x^(3) - 3x^(2) + 4x-1=0 has four distinct real roots x_1,x_2,x_3,x_4 such that x_1 lt x_2 lt x_3 lt x_4 and product of two roots is unity , then : x_1x_2+x_1x_3 + x_2x_4+x_3x_4 is equal to :

The equation x^(4)-2x^(3)-3x^(2)+4x-1=0 has four distinct real roots x_(1),x_(2),x_(3),x_(4) then find sum_(i=1)^4 x_i

If x^(2)+3x+1=0 then find x^(3)+(1)/(x^(3)),x^(4)+(1)/(x^(4)),x^(2)-(1)/(x^(2)),x^(2)+(1)/(x^(2))

The equation x^(4) -2x^(3) - 3x^(2) + 4x-1=0 has four distinct real roots x_1,x_2,x_3,x_4 such that x_1 lt x_2 lt x_3 lt x_4 and product of two roots is unity , then : x_2^(3)+x_4^3 is equal to :

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