" If "A=[[1,0,2],[0,2,1],[2,0,3]]" is a root of polynomial "x^(3)-6x^(2)+7x+k=0," then the value of "k" is "

If int_0^1(3x^2+2x+k)dx=0, find the value of k

If -i+3 is a root of x^(2)-6x+k=0 . Then the value of k is :

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

If A=[{:(1,0,2),(0,2,1),(2,0,3):}] , then prove that A is a root of the polynomial f(x)=x^(3)-6x^(2)+7x+2 .

If a,a+1 are roots of x^(2)+3x+2k=0 then the value of k is

alpha&1/ alpha are roots of equation 4x^(2)-2x+k+7=0 then the value of k will be:

If int _(0)^(1) (3x ^(2) + 2x +k) dx =0, then find the value of k.

If the roots of the equation6x^(2)-7x+k=0 are rational then value of k can be

If A = [[x,1,-x],[0,1,-1],[x,0,7]] and det (A) = |(3,0,1),(2,-1,0),(0,6,7)| , then the value of x is a)-3 b)3 c)2 d)-8

If int_(0)^(1)(3x^(2)+2x+k)dx=0, find the value of k.
