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

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

If 2 is a root of x^(3) + 3x^(2) - 4x + k = 0 then the roots are

If -1 +i is a root of x^4 + 4x^3 + 5x^2 + k=0 then its real roots are

If -1 +i is a root of x^4 + 4x^3 + 5x^2 + k=0 then its real roots are

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

If the roots 4x^(3) - 12x^(2) + 11x + k = 0 are in A.P. then k =

A : the equation whose roots are multiplied by 2 of those of x^(5) - 2x^(4) + 3x^(3) - 2x^(2) + 4x + 3 =0 is x^(5) - 4x^(4) + 12x^(3) - 16x^(2) + 64x + 96 = 0 . R: the equation whose roots are multiplied by k of those of f(x) = 0 is f(x/k) = 0.

If 2 is a root of the equation x^4+2x^3-3x^2+kx-4=0 , then k=
