Given Expression f(x) =
if (x-1) is factor of above expression
then if we put x=1 in the above expression , then the expression should be 0
hence
k= -3
Result : k=-3

The fact that
is a factor of
means that
1
is the root of this polynomial, i.e.
=
.
It gives you k = -4 - 3 + 4 = -3.
Answer
. k = -3.
