Well, mwok. Let's try synthetic division on this one.

. Since is a factor, then .

Now then, we know the remainder should be 0, so....Code:-2 | k 1 k^2 3k^2 +11 -2k 4k-2 -2k^2-8k+4 ------------------------------------ k -2k+1 k^2+4k-2 k^2-8k+15

Solve for the two possible values ofkand you're done.
