HEY THERE HERE IS YOUR ANSWER PLEASE HAVE A LOOK ON IT.
GIVEN : X-1 IS a factor....this means 1 is the zero of the given polynomial.
put x=1 and equate it to zero u will get answer...
2*1+2*1-6+k=0
k=2.
second part of ur question can be solved by remainder theorem......find the zero....that is -2...put -2 in the expression simply
-2^4+3(-2)^3-4*-2-2
16-24+8-2
-2 is the remainder.
