" 1."2x^(4)-5x^(2)+3=0

The biquadratic equation, two of whose roots are 1+i , 1-sqrt(2) is A) x^(4)-4x^(3)+5x^(2)-2x-2=0 B) x^(4)-4x^(3)-5x^(2)+2x+2=0 C) x^(4)+4x^(3)-5x^(2)+2x-2=0 D) x^(4)+4x^(3)+5x^(2)-2x+2=0

If - 1 + i is a root of x^(4) + 4x^(3) + 5x^(2) + 2x + k = 0 then k =

If -1+i is a root of x^(4)+4x^(3)+5x^(2)+2x+k=0 then k=

Solve the equation x^(4)+4x^(3)+5x^(2)+2x-2=0, one root being -1+sqrt(-1)

The roots of x^(4) + 4x^(3) + 5x^(2) + 2x - 2 = 0 one root being -1 + i are

Solve x ^(5) - 5x ^(4) + 9x ^(3) - 9x ^(2) + 5x -1 =0.

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