Find all positive values for K for which each of the following can be factored. x^2 + x - k I don't even know where to begin on this one! By trial and error, I came up with -2 and -6. Are those right? Are there others?

Find the values of the polynomial for the given values of the variable. -x2-5x-6 x=-3 x=-2 I got 0 for the first one and 0 for the second. Am I figuring them wrong? (and that is an x squared, not 2x) -(-3)^2 -5(-3)-6 -(9)+15-6=0 Thanks! you are right in both cases -x^2-5x-6...
